Trailer Temperature Rise

We did an experiment to see what the temperature inside our trailer would get to if it was all closed up on a summer day. It does get HOT!

This test ran for about a half an hour or more so I expect that it could get hotter still inside when it is all closed up.

CLICK HERE to see the test if you are interested. What I want to know is what some people do to keep it cool inside without AC. Imagine you are in an area with no power and it can get really dusty...

Basically the results look like this...


Outside Temp


Inside Temp

Oh God - tell me that's a joke. You didn't! It's hot enough with all the windows open.

Those temperatures are normal outside everyday here in west Texas during the hot summer season, can you imagine the temperature inside your trailer out here in the desert?

Shade Cloth

We are already talking about putting shade cloth over the top of the trailer and fastening it down on the cleats to at least keep the top cooler. If we orientate the trailer east-west the sun will not shine too much on the sides. All of this should help....

I'm with the guy from Texas. It's usually hotter than that OUTSIDE here in Oklahoma in the Summer. I have my Argosy parked in the shade and I really think that nice tan color keeps these trailers a little cooler. 90 degrees doesn't seem that bad to me. I too have been working inside without air conditioning. Just put in a nice fan and go for it. Judy

I've seen mine at 119*F, here in the Florida sun. My A/C seems to cool it right down, especially after the sun goes down.

Don't forget the Heat Index!

We have been getting the same type of temps around here too. Unfortunately my trailer sits in full sunlight...The fan helps...to a point but with 95 degrees and 80% humidity it is like sitting in a tub of luke warm bathwater I am planning on rerigging the thermostat on the AC so I can at least try and cool it off while I am working. Also plan on coating the top center roof panel with an Elastomeric coating of some sort...eventually. I have also considered making some type of cover that will slip over the open window itself to give added shade. I recall seeing a set of these on an Excella somewhere..

I have used my Scamp 16' twice this summer, and been in both the Behemoth and the Scamp quite a bit. It's amazing to me how much cooler the Scamp stays than the Airstream. I haven't done a formal temperature survey between the two, but I'd be willing to guess that there's at least a 10* difference. I've stayed in the Scamp for two, one-week stints while working on my apartment building in 95*+ temps and high humidity, and I have to keep the little A/C unit on low cool at it's warmest temp setting to keep the interior from freezing over! The Airstream, OTOH with the 13.5k BTU won't cool down enough to be comfortable!

Sounds to me like you need a 15k BTU upgrade Rog. I felt the same way with the 11k unit with the Bambi. Jack had the 13.5k unit in his 27' Safari and had similar findings. He too now has the 15k unit.

Heck, I've seen several new 34' new units with two A/C units (one front, one back).

Imagine you are in an area with no power and it can get really dusty...

Interesting. We found that in 95 degree heat and 70-80% humidity (by which I mean the International Rally in Springfield MO), our dark blue-green painted Argosy would reach 104 degrees internally if left sealed up in the sun. Our record, on an even hotter sunny day, was 108.

Your results of 100 degrees + suggest that a silver Airstream would get nearly as hot.

Several times we have had to cool the trailer down after a day of towing in the sun. Running both the Fantastic Vents with all windows open will cool it in a couple of hours, but your results will vary according to the outside temperature, and also the amount of "stuff" in the trailer. All those items inside get "heat-soaked" (especially if you have lots of clothing) and thus the trailer cools down more slowly.

If we can't cool the trailer down due to high ambient temperatures, we cool ourselves instead. Cool showers, swimming, or playing with a garden hose all work well.

BTW, when we have 30 amp power available our 1970's 13.5k BTU Armstrong does a fine job.

We use 2 fantastic fans and I just put a coating on the roof last week, won't know how much difference it makes for a couple weeks when we go to the rally in Mich. We won't have air till later this year. Marvin

Pick is right.Where i live we have been getting heat in the upwards of around 95 with a heat index of about 105 or so.This has been a really hot year for us.Then again i live on the beach and there arent really that many trees around.The crazy part is,We still have another couple months before it starts to cool down.Whew!!!!!

Since Land Rovers up untill the 1990's didn,t have airconditioning as an option, they offered a " tropical roof". For those that don't know, all of the body panels on a Land Rover are aluminum held together with rivets much like an Airstream. The tropical roof was another roof raised on very short legs above the main vehicle roof that allowed air to circulate between the two keeping the inside cooler, there was also oval ventilators that you could pop up from inside that would allow airflow directly into the Land Rover. It worked really well. It's certainly possiable that this could be done on an Airstream. Admittedly it woulld take some ( a lot) of engineering.
