7 tips for hot summertime travel

It’s May, and we’re gearing up for summer travel—and that means gearing up for heat.

Perhaps heat is on my mind because we’re in Arizona right now and the temperatures are already hitting the nineties every day. With an Airstream it’s usually easy to get out of the heat—after all, we have wheels—but there are times when it’s inescapable for a few days, like when we are crossing the Great Plains states. Many times I’ve been crossing Kansas or Oklahoma or Missouri and been nearly steamed to death in what the meteorologists call “oppressive humidity.”

So even if you plan to drive away from the heat, you need strategies ready in case the heat follows you. Here are a few of the things I’ve learned over the years:

1. Air conditioning is miraculous—but not magical

First off, if you have delicate pets or humans traveling with you, don’t mess around: get a campground with 30-amp or 50-amp power and plug in. This may necessitate a change in plans and you might end up somewhere you don’t want to be, but the blessing of cool air blowing in from the A/C will make it all worthwhile.

I find that a lot people are surprised to discover the limitations of a single air conditioner on a 30-amp plug. If you’ve got a newer Airstream with dual air conditioners (and a 50-amp plug) you can deal with just about any level of heat. But a single A/C definitely has limits. The A/C will generally cool the incoming air by about 20 degrees, but that doesn’t mean your trailer will be 20 degrees cooler, especially if it’s sitting in the sun. That means on a 105-degree day, the trailer interior might be well into the upper 80s until after dark.

So it’s useful to park in shaded campsites, preferably not in asphalt parking lots (green surroundings = cooler air), and be realistic in your expectations. If the trailer is over 100 degrees inside when you arrive, it’s going to take a while before the air conditioner can remove all the latent heat that is stored in every object in the interior.

To cope, try to spend the few couple of hours somewhere else (like a restaurant or visitor center) while the air conditioner does its job. Don’t even dream of using the stove or oven—the burners can output much more heat than the air conditioner can remove. If you have a microwave use it instead, or go out for dinner, or cook outside, or eat a cold dinner.

2. Boondocking requires special skills

Not many people will choose to spend a night in extreme heat or humidity without air conditioning, but someday you may find yourself in an unexpected situation where you must. (Maybe a breakdown in a remote area, a power outage in the campground, or failure of the air conditioner, as examples.)

In this case, the keys to surviving a night in the heat are water and electricity:

Water, because you need to stay hydrated and a quick cool shower will go a long way toward keeping your body comfortable. In desert boondocking situations you can even soak towels and place them strategically around the trailer for evaporative cooling. I’ve always brought a few gallons of extra drinking water when heading into a boondocking site in the summer.

Electricity, because you’ll use a lot more battery power than usual with the vent fans running constantly. A single Fantastic Vent (the kind installed as original equipment in most Airstreams) might draw about an amp of power, which isn’t much for short durations. But with two of those fans running around the clock for a weekend, you’re looking at something in the region of 90 amp-hours, which is going to overwhelm the typical 2-battery setup in an Airstream trailer. You’ll need to plug in, or have an auxiliary source of power: solar panels, generator and/or a much larger set of batteries.

3. Beware the melted power plug!

If you’re plugged in, be aware that heavy use of air conditioning can result in a melted power cord, which can be disastrous. This is caused by corrosion building up on the prongs of the plug. Corrosion makes the brass prongs of the power cord look dark brown or black. If you see this, clean it off before you use your power cord again. (We sell a kit in the Airstream Life Store specifically to prevent this.) Failure to do so will cause the prongs to heat up and melt the plug. Not only will that end your air conditioning, it can damage your Airstream or even start a fire.

4. Use the awnings and a Solar Shade

The Zip Dee awning that came with your Airstream trailer (or the equivalent awning on a Nest, Basecamp, Interstate, or Atlas) can make a big difference if it’s on the south or west side when you park. Definitely deploy the awning as much as you can to shade that side of the rig. If you’ve got window awnings, use those too as needed to cut the direct sun.) You should try to stop the sun from shining on the sides of the Airstream as much as possible.

A Zip Dee Solar Shade is a huge help too, when the sun is beating down on that side of the trailer, especially when the entry door is facing west.  The Solar Shade broadens the shady patch in the afternoon, when it really matters, and gives you a nice outdoor space that you otherwise wouldn’t enjoy on a hot day.

In an Interstate motorhome, you may find that the Mercedes dashboard air conditioning isn’t quite enough when traveling on the highway on a 100+ degree day, especially for any back-seat passengers. Sometimes you need to fire up the onboard generator so that you can run the roof air conditioner as you go. It might seem weird but it’s OK to do this.

5. Make sure your water hose can handle the heat

When you’re parked, you will probably discover that you don’t need to turn on the water heater. Often the fresh water hose lying in the sun, combined with warm water in the tank, will be plenty warm for showers. But there’s a downside to this: most drinking water hoses are not rated for “hot water” use. Cheap-o hoses made of vinyl or other plastics may leach chemicals when laying in the sun all day filled with hot water. That’s why we switched to drinking water hoses that are rated for hot water use.

6. Monitor the fridge and freezer

Keep an eye on your refrigerator as well. Often, RV refrigerators don’t have great ventilation and so heat can build up in the refrigerator compartment (the space behind the refrigerator). When the air temperature around the refrigerator’s cooling fins approaches 100 degrees—which is very common in the enclosed compartment, even when the outside temp is much lower— the result is warm food in the refrigerator.

To combat this, keep the fridge door closed, and if you need to get something be sure to get it quickly. It’s not like your home refrigerator that has a big compressor and can recover its coolness in a few minutes. Each time you open that door it can take hours to recover fully on a hot day.

If your refrigerator has a manually activated cooling fan, switch it on whenever the temperatures exceed 90. Some refrigerators have automatic cooling fans, others don’t have fans at all. If yours lacks a fan, consider having a set of electric fans installed in the chimney of the refrigerator compartment. These things are amazingly effective at moving hot air out away and helping the refrigerator cool down.

Also, get a wireless temperature monitor so you can check the interior temp without opening the door. You can get two of them and monitor the freezer as well, but I’ll tell you right now that if the fridge starts to climb above 50 degrees, whatever is on the door of the freezer will probably start to defrost. (Pack your ice cream and seafood in the back.) These wireless monitors are available from many sources and they’re not expensive.

7. Keep an eye on tire condition and temperature

As you travel on hot days you need to be extra aware of the condition of your tires. They are much more susceptible to problems and wear on hot days. When the air is 95 degrees Fahrenheit, the highway surface can easily be 120+, and the air inside the tires will often exceed 140 degrees at highway speeds. That’s brutal on tires and it shortens their life.

This is just one of several reasons I strongly recommend a good tire pressure/temperature monitoring system. Blowouts and other failures are far more likely on hot days, and you want to know right away if something goes wrong before it does additional damage. If you don’t have a tire pressure monitoring system you should make a habit of visually inspecting all the tires at every stop, checking the temperature with an infrared sensor, and checking air pressure frequently.

8 tools most Airstreamers should get now

You’ve got a new (or new to you) Airstream—what tools should be first on your list?

I’m going to assume you already have a sewer hose, a hitch, and other obvious things. Let’s talk about the things that you’ll learn you need through experience—without having the painful experiences.

Before I launch into my choices, a few disclaimers:

  1. This is by no means a comprehensive list. There’s probably a hundred more things that I could add. But these are some of the most useful tools and essential upgrades, in my experience.
  2. Not everything on this list is for everyone. Much depends on individual style: minimalist vs. survivalist, glamper or camper, hard-core DIY’er or “I always go to the dealer”. Think about how you travel, where you travel, and what sort of Airstream you have before you rush out to get new gear.

1. A tire changing kit

Your Airstream trailer did not come with a full set of tools needed to change a tire. (This is baffling to me. You get a spare tire, but no way to put it on.)

If you’re thinking that the tools that came with your truck will help, think again. The lug nut wrench probably won’t fit and the other tools won’t be much help when you need to change a tire on your Airstream. You need a dedicated Airstream tire changing kit.

Everybody should know how to change their own tires and carry the tools, even if you don’t actually plan to do it yourself. You may be physically unable to, but if you have the knowledge and you have the tools with you, then at least somebody else can change the tire.

The alternative is calling for roadside assistance, which might seem to be a great solution, but you’ll be sitting by the side of the road for hours, often in a place you do not want to be. Waiting to have someone come to change a tire for you is like waiting for somebody to come dress you in the morning. If you can do it yourself it is so much faster!

It’s not hard to change a tire. You can see the process in the video below, or read about it my book “The (Nearly) Complete Guide to Airstream Maintenance”—and we also include instructions in the Tire Changing Kit we sell in the Airstream Life Store.

We offer a Tire Changing Kit because it’s convenient to have one kit with all the tools in a single carry bag, but if you want to put together your own kit I’ll be just as happy.

The basics are a torque wrench (essential for correctly tightening the lug nuts when you put the wheel back on); a breaker bar (used for removing the wheel); an extension, and a correctly-sized socket. We also include a safety vest for roadside visibility, a pencil gauge to check the air pressure, and a six page instruction manual that explains exactly how to change a tire.

Tip: If you choose to buy all the parts separately, make sure you don’t skimp on the torque wrench. Cheap torque wrenches are not worth the money.

2. A cordless drill

It’s amazing how often I use my cordless drill for things other than drilling holes. On a trailer without powered stabilizer jacks, you can use a cordless drill with a socket adapter like this one, so you don’t have to kneel on your hands and knees in the mud to put your stabilizers up and down.

If you have a Hensley Arrow hitch, an 18 volt cordless drill makes quick work of tightening the strut jacks, and it’s also essential for the Hensley Hitch Helper (aka BAL Tongue Twister) if you have one of those.

I also find myself using the cordless drill to fix things around the Airstream. For example, on a recent trip the bathroom door’s hinge started to pull out of the door frame. With my cordless drill I was able to quickly drill a hole and install an additional screw to secure the hinge again—problem permanently solved in just a few minutes. Without it our trip would have been marred by a bathroom door that wouldn’t close until we got home.

3. A tool bag, with a few choice tools

I’m a big believer that it always pays to have dedicated tools for the Airstream. Not only does it save time, it ensures you always have the right tools in the Airstream on every trip. Don’t borrow tools from the garage for each trip, because you might forget them.

So start with a little tool box or (my preference) a tool bag. Make sure it will fit easily into the exterior storage compartments. Outfit it with the little tools you need most often during a trip, and the little parts that often need replacing.

Start with a few Philips screwdrivers. You can practically disassemble the complete interior of an Airstream with a single Philips screwdriver. You’ll find yourself tightening screws from time to time—they do occasionally work loose during trips. Some blue Loc-Tite will help keep screws from coming loose again or, to fix holes that have gotten too big to hold a screw you can carry a few match sticks and white glue.

Consider adding some of the following: adjustable wrench, pliers, a small “tackle box” for small parts like screws, spare fuses & fuse puller tool, teflon plumbing tape, silicone spray or Boeshield T-9, a few spare aluminum pop rivets in the correct sizes, a good quality rivet tool, sets of screw bits and drill bits for the cordless drill, utility scissors, a small microfiber towel, and some Parbond. Many of these items are in our Maintenance Essentials Kit.

I also like to have a headlamp so I can fix or examine things at night without having to hold a flashlight. A pair of disposable latex gloves can be nice for dirty jobs.

If you might get into little fixes or modifications to the 12 volt wiring system, then I’d add: electrical tape, butt splices, crimping tool, wire stripping tool, and a voltmeter.

If you have a Hensley hitch, I’d recommend a set of Allen wrenches and a grease gun (but you’ll want to keep that in the bumper compartment because it’s big and greasy).

4. A voltage monitor or (preferably) Electrical Management System

A plug-in voltmeter is really simple, and it will do a couple of very handy things. You just plug it into any outlet in your Airstream when you’re plugged into shore power, and it will tell you the voltage that you’ve got available—which is super important. It also verifies that there’s correct wiring at the campsite. It’s quite possible that the electrical pedestal at your campsite has a wiring problem, and that can actually be hazardous to your health.

There’s a reason we need to worry about the voltage coming into our trailers. We know that it’s supposed to be 120 volts, but rarely is it actually exactly 120 volts. Your appliances are going to be fine plus or minus ten percent, so from 108 to 132 volts. Exceed that, and you’re at risk of destroying certain appliances or even starting a fire.

Low voltage is by far the most common problem. An RV air conditioner typically can accept as little as 105 volts, but when you fire it up the compressor in it draws more power momentarily. So even though your voltage meter might shows 108 or 110 volts, you should keep an eye on it as the air conditioner starts up. If the voltage suddenly drops down below 105 for more than a few seconds, it is likely to burn out the motor in your air conditioner and you’ll be facing a big bill to replace the entire unit.

By the way, this can be a risk even if you’re in a fancy campground with shiny new wiring—especially on hot humid days when everybody’s pushing their AC to the max. Low voltage can still be a problem.

The best solution to this problem is an Electrical Management System (EMS, pictured at right). These devices check and monitor the power like a voltmeter but they also take action when something is wrong. If your EMS detects a problem, it will instantly cut the power to save your Airstream or appliances from damage—and it will automatically re-connect when it’s safe.

5. A rivet tool

A rivet tool is a surprisingly easy thing to learn how to use. Basically you just stick a rivet in the hole, hold it tight against the surface, pop the handle of the tool a few times, and the stem of the rivet breaks off when you’re done. It’s as easy as a screwdriver.

Don’t believe me? Check out this short video where Tothie demonstrates it.

Do you really need to travel with a rivet tool? Yes! Those little rivets on the inside of your Airstream break occasionally, especially after traveling a rough road, and there’s no need to haul your Airstream to a dealership just for that simple little repair. Just break out your handy tool and spare rivets, and you can fix the problem in seconds.

Also, someday you’ll lose a belly pan rivet, which is a more pressing problem. It happens because corrosion occurs where the aluminum belly pan and steel frame meet. The result can be a belly pan dragging on the road. If you have a rivet tool, a cordless drill, and the right sized aluminum pop rivets you can be back on the road in minutes.

It’s a no-brainer. There are 4,000-5,000 rivets in the average Airstream. You should be able to replace one of them.

6. MegaHitch lock

Storage facilities are not safe. I hear reports regularly from people who have lost their Airstreams out of supposedly secure RV storage equipped with video cameras. Once, some Airstream friends of mine found out that someone had broken into their stored trailer and thousands of dollars worth of their tools inside were all gone. Management didn’t even know—and it turned out that the videocameras were fakes.

Cheap hitch locks provide zero security. If you spend less than $100 on a lock I guarantee a thief could break it or bypass it within thirty seconds. Thieves can’t break a MegaHitch Coupler Vault PRO.

It’s not cheap, and it is heavy. But it works. If you’re keeping a $40,000-$150,000 Airstream on a storage lot, $200 is not a lot of extra money. You might also check with your insurance company. If you have proof that your trailer was locked with one of these, they may waive the deductible if it does get stolen.

7. Tire pressure monitor

A flat tire can do lot more damage to your trailer than you might think. It doesn’t just go flub-flub-flub as you come to a stop. Often you’ll have no idea that you’ve had a flat because it’s way back there on the trailer as it starts to shred. It rips up your Airstream, destroys the wheel, creates a hazard on the road, and it leaves you with a thousand dollars of damage that could’ve been prevented.

The TST tire pressure monitoring system is also not cheap, but it’s the best. I use it on every tow and it has saved my Airstream more than once.

8. A good water hose

Ultimate water hose from Airstream Life StoreYou can get drinking water hoses everywhere, and they’re usually pretty cheap—about $30. But the ones the RV industry pushes are really pretty bad. They kink, they have thin fittings that bend and leak after a year or so, and they fail regularly. Don’t even think of letting it freeze or get run over by a truck while it’s pressurized; the hose will burst. For these reasons, many people end up buying a new hose every year or so, which is not a good deal in the long run.

I could go on all day about how lame the typical “white hose” is, but instead I’ll just say this: get an Ultimate Water Hose. After years of replacing cheesy Wal-Mart and Camping World hoses, I finally decided to develop a far better one. We guarantee it for 5 years against any type of failure no matter what you do to it (other than cutting it with a knife).

Yes, it costs double what a cheap hose costs. But you won’t need to replace it for a very long time. Mine has been in heavy use since 2017 and I expect to keep using it for many years. If you want to read more about why you should ditch the ordinary water hose, read this blog entry.

Air conditioner “soft start” devices

Reader Cheryl V. has an interesting question:

“Have you heard of a device that helps start your AC slowly so that a 13500 [BTU] can run on a Honda 2000 generator?” she asks. “I forgot to ask about it at Alumapalooza.”

Now that summer is in full swing, temperatures are high both inside and outside our Airstreams and AC maintenance and operational practices are top of mind. Experts at Outside Interests have pondered Cheryl’s question, and think she’s asking about a “soft start” capacitor, like the Dometic SmartStart II.

It doesn’t actually “start the AC slowly”, but acts like a boost battery to take some of the initial load off the power source (usually a generator) when the air conditioner compressor starts up.

The short answer to the question? It’s not a good idea to try to run your air conditioner on a single Honda 2000 generator, even with this device.

Your RV air conditioner pulls a great deal of power when it ramps up upon starting, and can easily overload the typical 2000 watt RV generator—resulting in the generator shutting down or possible damage to the air conditioner.

A start capacitor stores power to help with this initial load, but it’s not able to make miracles happen. Even with a start capacitor, a 2000-watt generator is not a good match for the typical Dometic air conditioner installed on an Airstream. Dometic recommends at least a 3500-watt generator. Many Airstreamers have success with 3000-watt generators, or two 2000-watt generator running in parallel.

You might have read online that some folks allow their ACs to run from a 2000-watt generator, but please be careful. This goes into the same category as running the air conditioner on a 15-amp plug. It will work…until it doesn’t. And a burned-out air conditioner is an expensive repair. Look carefully at all recommendations, guidlines and warnings printed in the documents supplied with any product of this kind.

Hope that helps, Cheryl. Keep cool! Check out this other Outside Interests article about air conditioning for more information.
