How to Weigh Your Airstream, part 1

When you ‘stream by a truck stop and notice a “weigh station” sign, are you tempted to pull off and see what your rig weighs? Most new (and many expert) Airstreamers are intimidated to join the line of 18-wheelers—but don’t be. Most RVers report that they have a pleasant experience at the scales.

“It’s not scary to weigh your trailer,” said Jon Gold, Alumafiesta seminar leader. “And everyone should weigh their Airstream to make sure you haven’t exceeded any gross weight capacities.” Here’s how:

Load it up

Weigh your trailer when you are fully packed, “when you’ve got everything in it, ready for a trip,” advised Gold. “Food, water, clothes, pots and pans…anything you’re going to take along.” This also includes passengers and pets, and a full tank of gas.

Look for a CAT sign

—big and yellow, with a friendly cat’s head logo. A Certified Automated Truck Scale (“CAT Scale” is a franchise business) can be found “at most truck stops,” said Gold. “It’s only ten dollars, and if you weigh your trailer once when it’s fully loaded, you don’t have to do again.”

Pull up onto the scale until your driver’s side window is even with the intercom sign; painted lines on the scale will guide you as well. You’ll be required to push a “call button” that may be situated high above your head. (You could stand on your running board to reach it, or take this tip from those in the know: bring a stepstool, or better yet, a broom handle to punch the button.)

Have your trailer license number ready. A “weighmaster” will greet you, guide you through the process, and tell you when you’re done. Pull away, park, and walk into the building to get your scale ticket at the fuel desk. (The computer printout you receive includes gross vehicle weight as well as individual axle weight.) That’s all there is to it!

(Want more detail?  See our followup article on using the CAT scales)

Weigh twice

Typically a truck scale will provide three separate weights: front axle, rear axle, and trailer axles (all counted together). To get started you’ll need a baseline. Take your first trip through the scale without your trailer, so the report will reflect the amount of weight on each axle of your fully loaded tow vehicle. (Find the Gross Axle Weight Rating [GAWR] for both the front and rear axles in your vehicle owner’s manual, or on the sticker inside the driver’s side door jamb.)

Now hitch up your Airstream and pass through the scale again. This time your report will show all three axle weights: front, rear, and trailer.

CAT-scale-form

Compare the two reports, line by line. The trailer weight should be below the Gross Vehicle Weight Rating (GVWR) stated by Airstream. Find these specs for your coach on the serial number plate on the lower front streetside of the body, or on a sticker on the inside of a mid-closet door about 60″ from the ground. (2009 and later trailers also have max cargo weight on a sticker on the screen door.)

If you exceed any weight ratings—

“take stuff out,” said Gold. “I worry about the people who go to the Gem and Mineral Shows,” he laughed. “But don’t take out the tool kit!” It’s easy to overload your Airstream without even knowing it. If your trailer is too heavy, you must reduce your cargo before going further.

Tire inflation matters

An overweight Airstream and under-inflated tires are a bad combination. Look on the sidewall of your tire for the recommended tire inflation pressure and adjust accordingly, and stay on top of optimum tire pressure with a good monitoring system; find one at the Airstream Life store. “When you’re rolling down the road, it’s almost impossible to feel when a trailer tire loses air pressure,” cautioned Rich Luhr, Airstream Life publisher. “Most people find out far too late.” The tire pressure monitors—as with all items in the store—“are the things we tell our friends about,” said Luhr. “Things that can save your Airstream from disaster, or improve your travel experience.”

Secrets of Power: The Xantrex TrueCharge 2

Most travel trailers are built for weekend use. That mean the factory equips them with a battery or two that is sufficient to power the trailer for about two nights without being plugged in. After that, it’s time to find a source of power.

So it’s not surprising that not long after an Airstream owner begins to travel a bit more away from the KOAs and toward bucolic and private boondocking sites, they begin to look for ways to extend their power capacity. The next step is often a generator or solar panels, and a new set of batteries with greater capacity. Absorbed Glass Mat (AGM) batteries such as Optima and Lifeline are a typical choice because they last a long time, can be deeply discharged, and are maintenance free.

But then an interesting problem crops up, one that most Airstreamers—and even many RV repair technicians—don’t know about. The power converter built into your Airstream isn’t optimized for charging AGM batteries. Often it will undercharge them, particularly in cold weather.

People tend not to notice this unless they have also installed a highly accurate battery monitor, because the factory installed monitors are only rough estimators of the battery state of charge. So they are often misled into thinking the batteries are being fully recharged. But incomplete charging results in shortened battery life. Batteries will only have their longest possible life if they recharged to full after every use.

To truly get the most out of your new AGM batteries you need to replace the factory installed power converter too.

Only a few brands of power converters have the built-in capability to provide the correct voltages needed for AGM batteries. For this review, we upgraded an Airstream Safari to a Xantrex TrueCharge 2 (60 amp model) to see the difference in performance and the ease of installation.

The conversion job is fairly straightforward for a handy person, taking about 2-4 hours. Installing the Xantrex is easy; it’s removing the old converter that gets into a little mechanical surgery, because the factory charger is built into the same case as the fuse panel and circuit breaker panel. Separating the lower charging unit from the rest requires a drill, wire cutter/stripper, screw drivers and Torx drivers, a nut driver, and a few other basic tools. (Documentation for this job with photos can be found around the ‘net by Googling “replace power converter Airstream”.)

Once the old power converter is removed, installation of the Xantrex is painless. The Xantrex TrueCharge 2 is a beautifully crafted device that looks like it should be on display somewhere. As one friend commented, “It’s way too pretty to be installed inside,” but indeed that’s where it goes. It screws down to the floor securely, and then connecting it is a matter of butt-splicing six wires (ground, DC – and DC+, and three wires for AC), which takes only a few minutes. Since it’s designed for marine and RV use, everything on it is marine grade. Providing rubber covers for the wire connections is a nice touch, typical of this high-end unit.

The TrueCharge 2 is pre-programmed for 3-stage charging of “wet cell” batteries. Changing settings to provide optimal charge for AGM batteries is a matter of pressing two buttons. Once done, the output voltage jumps to the correct level for AGMs, which means those batteries will be charged to their fullest capacity. This was the feature we were looking for in our test Airstream, since other brands such as Parallax and Intellipower provide just one output voltage for all types of batteries.

The TrueCharge 2 can also support up to three separate battery banks, and can even run in parallel with a second charger for really large installations, but most Airstreamers won’t need those features. A single 40-amp or 60-amp TrueCharge 2 will be sufficient to replace the original factory unit.

TrueCharge Remote
TrueCharge Remote

The LED display on the case shows exactly what the unit is doing (rate of charge, type of battery, etc), but since it will be hidden out of sight, adding the optional Remote Panel is a wise choice. This panel connects with a simple telephone-style cable, and can be mounted on the wall anywhere within 25 feet. As a bonus, the Remote Panel adds a few features that the onboard TrueCharge 2 display doesn’t provide. If we are to be totally honest, it is also just plain cool-looking. You might never touch it again, but all those colorful LEDs certainly make for a nice display.

Battery Temperature Sensor
Battery Temperature Sensor

A particularly useful option is the Battery Temperature Sensor. This measures the temperature of the battery and allows the charger to compensate. Warm batteries need lower charging voltages; cold batteries need more voltage. If you simply slip the sensor over the negative post of the battery and run the provided wire back to the TrueCharge 2, it will figure the optimal temperature compensation automatically. If you don’t use the Battery Sensor you can still manually compensate for temperature using buttons on the Remote Panel.

Interestingly, since the TrueCharge 2 was designed for worldwide markets, it can accept input voltages of 90 to 265 volts AC. With that and other protections built into it, it’s unlikely to be damaged by excessively high or low voltage at the campground. It also has a battery equalization (or “de-sulfation”) mode that helps maintain the batteries.

Once the TrueCharge is in place and power is applied, it checks the batteries and then starts silently maintaining them. Although it has a built-in fan like the original converter, it rarely runs and when it does it’s much quieter. It’s also considerably lighter than the old converter because it isn’t mounted in a bunch of heavy sheet metal. Overall: it looks, feels, and operates like the major upgrade that it is.

Xantrex is known for premium products, and the TrueCharge 2 doesn’t disappoint. Running about $600 online for the 60-amp model, Remote Panel, and Battery Temperature Sensor, it’s a good investment for Airstreamers who like to get the most out of their power system. Smart, well-designed, flexible, and in every way an improvement over the original gear, it’s a device befitting an Airstream.

How to Weigh Your Airstream, part 2

Here’s a bit more detail on how to use a truck stop scale, following up on our previous article “How To Weigh Your Airstream, part 1“.

“Don’t be intimidated by the truck stop and the Big Truck dudes there,” says Lexie Kensington, an avid vintage owner. Here’s more you need to know about weighing your rig:

“A weigh costs money. Usually about $10, but each additional weigh for the same equipment is only $1 extra for a 24-hour period at the same scales. The weigh will come to you from a licensed weigh master and is a legal document. Sometimes it will be stamped or embossed like a notary seal. It will show the individual scale sections and the total of the entire combination of equipment.

Never drive on a scale the wrong way. Wait your turn if there is a line which almost never happens. It’s painless, easy, and the employees at the truck stop will be glad to help. They work hard for lousy money. By just being a cheerful customer you’ll make their whole day.

The scales platform you drive onto is in two or three sections. Usually each section is marked by yellow or white stripes. These sections are for semi trucks to place the steering axle, the driving (rear) axle of the tractor, and the actual trailer on individually. The tractor and the trailer are weighed in two sections, on two scale platforms.

For best results, go onto the scales all packed for your intended trip, tow vehicle along, with your Airstream, kids, pets and spouse.

Unhook and park the Airstream in a section of the lot out of the way of other traffic. Note: It is considered poor form for a semi-trailer driver to “drop” a trailer and unhook at a truck stop, evidently abandoning a load, or engaging in some other suspicious behavior. As an RVer, you have more latitude, but be courteous in using up blacktop space.

Drive onto the scale platform when clear, with your passengers. If you can, park with your steering axle on the most forward platform, and your driving (rear) axle on the platform just behind it.

Your rig might be too light. Some scales are are set up so that the modest weight of your tow vehicle divided between the two platforms does not register on their equipment. In this case you may need to get both of your tow vehicle’s axles on the most forward platform. It will fit, but you may need to get out and inspect it.

Call for a weigh. There will be a push button call box located for the semi tractor driver to push and ask to be weighed. Since most of the calls for weighs are by semi drivers, it will be far out of reach from your tow vehicle’s window!

An almost unintelligible person (many times a young overworked lady) will holler “COMPANY NAME?” meaning to which trucking company should the bill for this weigh be sent to. You should respond “private weigh,” meaning you are going to come inside and pay for this on the spot. While this is unconventional, they will understand that you are not a big semi tractor.

After a few seconds, they should call back or signal you that they have the weigh. Pull off the scales, go inside to the Fuel Desk and identify yourself as the person with the “private weigh” and they will charge you and hand you the certificate.

Now is a good time to review the weigh and see what your different axles are bearing. With your tow vehicle’s published data, you’ll see what each axle is rated to carry and what it is actually carrying. Also you can see what your tires are carrying per axle, and if you need to unload or leave a family member at home after all. If the numbers are all inside the published guidelines you can proceed. If not: UNLOAD SOME STUFF! Some like to leave a safety margin of +/- 10%

You’re half done. Now hook up your trailer and again drive onto the scales, with steering axle, driving axle, and trailer axles sets all on their own platform if possible. Ask for a Private Weigh again, wait for the weigh master to get the data. Pull off, park, and get your additional weigh (it should be only $1 this time) and review the data. You can now deduce the following:

The hitch weight (the static pressure on the hitch ball) is your second driving axle weight subtracted from the first. Have you overloaded your hitch? Check against the published numbers of your hitch.

The gross weight of the trailer is the trailer platform weight plus the hitch ball weight. Are you within the weight range of your trailer’s gross weigh limit? If you exceed it, your brakes will be mighty unhappy.

The weight on your trailer tires is the trailer platform number. Are you over? Are you inflated correctly to manage this load?

The weight upon the rear tires of your tow vehicle (the driving axle platform number). Are you over your driving axle or tires limit? It will be different (heavier) now that you have the trailer hooked up!

And finally—how much weight has your front axle lost by the weight of the trailer pushing down on the rear? (Second front axle weigh subtracted from the first.) Do you need to adjust your weight distribution system? If driving feels uncomfortable with that weight loss on the front axle, you can fine tune it by successive weighs. At only $1 per, it’s cheap insurance. Insufficient weight on the front axles can make steering feel weird, and in an emergency, leave you without good control if you have to make a sudden-avoidance maneuver.

Don’t be intimidated by truck stops, folks who use them, or those who work there. They all wish they could be you: enjoying RVing with an Airstream!

Electronic Security Tips

Airstreamers are becoming more and more dependent on the wonderful mobile devices that save us time and precious space inside our aluminum homes—and that’s a compelling reason to take a hard look at electronic security and backup options.

“I don’t want to be a bummer here, folks,” said Rich Luhr to his seminar audience at Alumafiesta, “but if you have a lot of data on your phone, or your laptop, or your tablet, it’s time to get serious about securing your devices and backing them up against failure.”

Luhr, Editor and Publisher of Airstream Life, offers the following smart tips. (Warning—reader discretion is advised. Until you adopt these measures, you might have trouble sleeping at night.)

There’s an app for that.

If you own an iPhone, iPad, iPod touch, or Mac, download “Find My iPhone”,  free from the app store. (Similar apps are available for Android devices.) If you misplace any of these devices, use this app on another device to locate the one that’s missing— or protect your data by remotely locking it, or even erasing all of its data. “Lost Mode” locks your missing device with a passcode and can display a custom message and contact phone number right on the screen—and you can keep track of where it’s been.

Basic rule #1: Password protect everything.

If you leave your machine on “sleep” without securing it with a password, someone, anyone, can wake it up and start snooping—or stealing. “Password protect all your devices, and don’t use the same password for every device or every service you use,” advised Luhr.

Get serious about regular backups.

“How many people are willing to admit you don’t back up your computer?” asked Luhr. (You know who you are.) “You need to get on a regular routine. A hard drive failure on the road is one of the worst things that can happen to you. You’ll be using the computer and suddenly the hard drive starts making a funny noise, and twenty minutes later it’s gone. Hard drives fail. It’s not a matter of if, it’s a matter of when.” You’re at particular risk if your computer is more than three or four years old. The time to back it up is now.

Consider carrying a portable hard drive in your Airstream for every computer you own, and run backups on a regular basis while you travel. At home, keep a second set of backup drives in a fireproof safe. “If your Airstream burns to the ground and you lose your laptop and backup, you’ll have files to restore, safe at home,” said Luhr. “Think about all the thousands of photos you’ve taken over the years, or that people have sent you—pictures of your grandchildren—images you could lose and never get back. Have one backup with you, and one away from you.”

Mac users, try Carbon Copy Cloner or use the built-in Time Machine backup utility. Backup before every trip, and often even when you aren’t traveling.

Your compromising data is already out there.

And no, we’re not talking about those nekkid pictures, either—your email inbox is filled with far worse. “All your old email is archived unless you actively delete it,” said Luhr. “When the wrong people get ahold of your email they start skimming through it; that’s the first thing they do when they steal a laptop,” he said. “They’re looking for passwords, log in IDs, social security numbers—anything that you’ve emailed or might have been emailed back to you that can be used to break into your accounts. If they can break into one, sometimes they use that to break into another, and it becomes a cascade.”

Luhr told the terrifying tale of someone who lost his computer—and nearly his identity. Using data found only in email, hackers entered his Amazon account and leapfrogged from there to find credentials, codes, recovery passwords and Apple ID. Eventually they even wiped his hard drive by remote control. “Everything went out the window,” said Luhr, “including irreplaceable photos of his daughter when she was first born.”

Encrypt your hard drive.

Meaning, you’ll set a password for your computer, and need to type it to unlock it every time you use it. “This takes you just a second,” said Luhr. “It’s simple. If somebody steals your laptop or hard drive, they can’t crack it.” Consider using full disk encryption on your laptop if your job depends on it.

Be cautious about public wifi networks.

“I don’t like ‘em,” said Luhr. “I think if you have the choice of your own cellular connection—your phone’s ‘personal hotspot’, MiFi, or Jetpack—that’s a far safer way to do anything online. Public wifi can be hacked.”

If you do use one, make sure it’s one you know; your KOA-supplied connection is safer than the dreaded “free public wifi”. If you see that in your connection drop down menu, “run away,” cautioned Luhr. “That’s what hackers use as their ID to try to get you to join it.”

Sadly, it’s no longer safe to use the computers in a cyber cafe or hotel business center, either. “Unless you’re just printing, do not use any public or borrowed computer for any site that requires login. It’s not worth it,” said Luhr. “That computer could be compromised in so many different ways. We all have our own computers now. Don’t use any other unless it’s an absolute emergency.”

The next big thing: Two-step authentication

“Passwords are becoming passé,” said Luhr. “They’re not enough anymore.” For one thing, they’re too easy to guess—the most popular choice is still “password”, followed by the equally lame “123456”—and even a word that’s special to you is subject to computer-generated “dictionary attack”. “Sooner or later if you’re using a real word—something like ‘airstream’—they’re going to get it,” said Luhr. “It’s just a matter of time.” That’s why you’re likely now building your passwords from a combination of lower case letters, an uppercase letter, numerals, and symbols. (When you choose a new password, keep submitting ideas until its designation moves from “weak” to “strong”.)

“All they need is that one piece of information to eventually get into all your accounts, which is why two-step authorization is a great system for enhancing security,” said Luhr—especially for sensitive sites (like a banking service) that are restricted to absolutely everyone other than you.

It’s simpler than it sounds: two-step requires something you know (like a pet’s name) along with something you have (like your phone or credit card). When you key in your password a site will “know” your computer, but will be suspicious if you log in from another device; you’ll then be required to prove that you know more. A popup alert will announce that a security key—usually a 6-digit code—has been sent your phone number on file; use that code to enter the site you need back on the computer. “That’s a one time confirmation, that proves that I know the password and I’m holding the phone in my hand,” said Luhr.

Once considered overkill, two-step authentication is now becoming commonplace, and only takes a minute to set up. Definitely use it for high-security, financial applications whenever available—and consider it for email, websites, even social media, too. “Any service that offers it does so for a really good reason,” said Luhr. “If they offer it, give it a try—particularly for your email. That’s the biggest security hole that you have, with the most information about you in it.”

“Even social media gets hacked,” said Luhr. “Facebook, Twitter, Instagram—and it only takes one hack for people to get a lot more information about you than you ever thought possible. It’s almost eerie how much information is online these days, even for those of us who don’t go online.”

Get a password manager.

So now you’re fortified—good for you. Every device you own is secure and recently backed up, and all your online accounts are password protected with a different combination of letters, numbers, and symbols. But, c’mon. How are you supposed to remember them all?

“You’re right,” said Luhr. “You’ve got two hundred different passwords, and I’m sorry, but none of us over fifty are going to remember them all. It’s not gonna happen.” And writing them down? That’s a bad idea. “My mother did what a lot of people do: wrote all her passwords down on a big piece of paper and tacked it to a bulletin board, right next to her computer. If somebody broke in and took the list, that would be a disaster. I said ‘Mom, you need to get a password manager’.”

There are several good ones to choose from, and Luhr uses mSecure. “It keeps all your passwords, on your phone, in encrypted form where they can’t be hacked, always with you, in one safe place,” he said. “All you have to do is remember the password for mSecure.” (Of all your passwords, this is one to ensure it’s rated “strong”.)

Log in and tap to look up your passwords and associated handy details, including the URL it belongs to and usernames. The passwords appear as a series of dots, obscured until you’re ready, from prying eyes that may be looking over your shoulder.

“It’s one of the more expensive apps you’ll buy,” said Luhr, “but I strongly recommend it. Think about the cost of the information you have. Data security is the reality of our lives today.”

MüvFree Computer Stands

Too much sitting—including long hours behind the wheel of our vehicles—coupled with continually looking down at computer screens is “wreaking havoc on our health,” said Kephart “Kep” Taiz, creator of the innovative MüvFree furniture collection. His adjustable computer stands raise screens to eye level and allow the user to stand or sit, improving posture and encouraging movement while you type or work online.

Essentially, the stand tilts and angles your laptop—conforming it to your body, not the other way around. That means less fatigue while you work, and less chance of injury. If you’ve ever had backache or wrist pain while working at your computer, you’ll see the value in the MüvFree stands.

“Airstreamers are one of my niche demographics,” said Taiz. “Our mobile, sit-stand desks are ideal for working in compact spaces, and the multifunctional all-wood designs can be integrated into the Airstream office to create a range of comfortable positions for working with tablets, laptops and books.”

MuvFree Slide Stand
MuvFree Slide Stand

The MüvFree desktop stand may be the ideal portable workplace for Airstreamers who desire a more ergonomically correct and comfortable way to use a laptop computer while traveling. MüvFree units are priced from $150 to $400, and come in three configurations: the highly portable “Lift” model, the “Leap” (a larger design best suited for home or office use), and the “Slide” which makes it comfortable to work from your bed, gaucho, or banquette. It can even be hung from the wall. Outside Interests staff used the Slide model during Alumafiesta in Tucson, and field tested the device later at home and in a mobile Airstream office.

The attractive, mod Slide is made of hand crafted birch wood, is reasonably light (a little over six pounds), and can be adjusted to an infinite combination of angles, heights, and distances relative to your body.

It’s easy to use: Clamp your laptop or tablet securely to the stand with soft rubber grabbers, then adjust the frame to the exact position that makes you most comfortable. Taiz recommends standing, to reduce pressure on the neck and spine while encouraging frequent changes in posture.

The Slide folds down to a manageable size when not in use (but probably stows best in your tow vehicle if you own a Bambi). Each MüvFree stand is currently hand-built by Taiz in Tucson, and his designs continue to improve as he experiments with new materials. For example, the Slide we tested was optimized for 13″ laptops, but a revised model with new clamps that are better suited for 15″ computers is on its way.

If you find that your MüvFree stand is difficult at first to adjust, we did too—but that was due to the fresh varnish, recently applied. A little furniture wax and the moving parts should glide easily into the configuration you’re looking for. (Taiz has also just updated that model with a new type of gasket for easier adjustments.)

When you see the MüvFree stands, you can see the roots of their design in Taiz’s enthusiasm for yoga and minimalist design. The light bamboo and birch materials will look good in your late-model Airstream, and accent colors can be hand painted to coordinate with your decor.

Product availability will vary, based on Taiz’s production schedule. Learn more at müvfree.com
