Evaporative cooler
as defined by Wikipedia:
An evaporative cooler (also swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate (that is, it has a large enthalpy of vaporization). The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). This can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants.
If one googles the term there are plenty of alternatives to air conditioning, some of which are battery powered, thus easily used in your Escape. This one only draws 2 amps to charge it's internal battery. https://www.amazon.com/dp/B087B5KHBB...xpY2s9dHJ1ZQ==

You typed all that just to use the word enthalpy, didn't you?

The key is "dry air". Evaporative cooling does not work with humid air. (Which is why sweating in humidity does not cool you off whereas in very dry air you seem not to sweat and feel more comfortable- the evaporation of moisture from your skin is immediate and cooling.)

I have used one and it feels more comfortable than without here in the Mid-Atlantic area. Perhaps in deep south I do not know but more than 2/3 of the states it could be an alternative. Here is the one I used years ago, it has been replaced with a USB battery powered unit. Works great at rest stops and sleeping in your Escape with just the fan on.

Isn't that one the one with ice in it? That's a little different than pure evaporative cooling as it starts with a colder medium. That does help some- with or without evaporation. But having lived in a house in Fresno with only evaporative cooling I can tell you that even moderately humid weather drastically decreases its effectiveness.

🤔 how does all this extra moisture exit our fiberglass trailers?
It doesn’t create a mold problem?

You have you maxxfan on and there is air circulation, more than what is there in the winter. Besides it is on only for a couple of hours. I'm not saying you close up the trailer and use this in stead of a/c, I'm saying this will make it feel better than without a/c.

No more than being in Houston with 100% humidity.
I have treated all the trailer wood with Mold-Care and sealed all the exposed wood surfaces with urethane varnish where I could. https://www.domyown.com/boracare-wit...SABEgIhMfD_BwE
I had mold starting to form within six months of getting the trailer back from Chilliwack - not good. The pic below is where the bed supports started showing mold. It grew from there and I replaced all the affected wood with new treated wood.
The fridge compartment was the worst as it is open to the outside air so I completely sealed that area.
Much better now - I haven't seen any mold since.
