Fellow desert dwellers AC question

All,

just picked up a 2016 Thor Outlaw 37RB. So far it's pretty slick. Been dig'n it on our first trip this weekend. We had a 2000 Class-A previously and sold it about a year ago. It was a really low-end, short DP, but we loved it. Anywho.. My question is regarding the AC.

This unit has dual 13.5K BTU AC units. One just behind the drivers/passenger seats, then one just aft of the kitchen. There is a window-style AC unit in the garage part that works pretty well, but we've kept that all closed off for the most part.

We're camping at Lake Mead in 105+ temps, no shade and it seems our AC units can't keep up. I'm not sure if they are not working 100% or if this is just simply too extreme for them. We're getting cold-ish air out of them, but set on full-blast (60 deg) we can't get the coach down below 80. It's just brutal in here. We have all the blackout shades pulled, the toyhauler is closed up, and all 3 ACs running on full blast. We're not cooking or doing much of anything inside. In fact we left for about 4 hours this morning, and came back and it was still 83-84 inside.

My question is, should a coach like this be able to get cool (into the 70's) under these conditions? I don't recall our old RV struggling this hard, but I might be mis-remembering.

What do yall think?

I run air with my Li 48v pack, and was surprised to find that with just one positive cable, the connector on the ceiling of that box was getting very hot. There are bolts that go through and connect to busbars.

So I doubled it up. You wouldn't think that just 22 amps would heat things up like that! Perhaps the bolts and connectors up top are undersized, not the cable itself, because the cable is plenty big.

I keep thinking on these lines when retirement comes. I want my panels to not just cover the roof but slide out maybe four feet on each side to give shade. With 3 to 5 kW solar and a Powerwall battery I will be running the air 24/7 off solar :B


I keep looking at those Tesla home solar batteries. I keep thinking, why not?

I have been trying to figure out a way of using the dash AC to supplement the roof units without running the main engine. Either put an electric compressor in parallel with the engine driven on or just replace the engine driven one altogether. The dash AC seems to work as well as the roof units and is much more pleasant to run. Has anyone figured out a way to do this?

I have never camped in the desert BUT, ...

I am amazed that someone has not figured out some kind of sun shade that would cover major portions of the roof. Fabric or even screening to the wind can blow through. Get the A/C units in the shade make a BIG difference.


Come on out! ๐Ÿ™‚ The desert heat/sun will laugh at any sort of screen. It's just simply a hard time to camp out here. Really nice at night, but the days are brutal. I'm thinking maybe I'll just cover the roof in solar panels, that will deflect the heat and give me power!

Come to the desert and camp, but do it Oct-April. You'll love it. No bugs. No moisture. It's the cleanest camping you'll every do.

It was rare...that was the first year I had the Vogue....so that would have been 2002 or 2003. I had always wanted to go to Terrible's Lakeside Casino/RV Park....Loved it even with the heat. I think they have gone downhill a bit in recent years...

That's rare for that early. What year was that?

With all this being said, just to debunk the 20 degree lower that "outside" temp again(as others have tried), when I first got my present MH(a Vogue well insulated), I had 2 13.5 BTU airs, full awning and not much shade but they did have grass instead of concrete all around. I was in Pahrump, Nv in late March early April, the temp reached 117 degree's and I can guarantee that if it was 97 inside the MH I would have given up RV'ing right than and there. I've been called a liar many times so have at it, but my temp in the MH was in the mid 60'ies!!! My wife and I were wearing sweatshirts.


I've repeated this on a few occasions and other times had difficulty in maintaining mid to high 70'ies but I'm talking 100 + conditions. I couldn't travel with my dogs if I couldn't keep them at least somewhat cool. I've talked long enough!!! ๐Ÿ™‚


I too have camped many times in 95-100 degree weather, I have two 15,000 BTU ac units and have never had a problem keeping the coach cool, maybee it has to do with our Year Coach, they don't build them like that anymore.

I don't have any doubts. I use the foil bubble insulation on all windows (especially on the windshield), have blackout curtains, have awnings on all windows, keep the coils on the A/C clean, keep a fan circulating the air, etc, etc, etc. I live in Texas and extreme heat is the norm but we most always stay cool in the m/h. Yeah, it's dark inside but when choosing between 70 degrees dark and 90 degrees and a nice view, I decided I could walk outside and get the view.

Your 2 A/C's will never be able to keep up with that kind of heat. What you are experiencing is about right. You can buy a portable A/C unit at Lowes/Home Depot for those really hot days or you can add a 3rd roof unit to your RV.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?

I have not yet tried this stuff but thinking about it. "Bus kote" is what is on the roof of a lot of school buses and contains ceramic beads that supposedly reflect heat. If you google there are a lot of testimonials. If you try it let us know the results.

Youmsy find that the front cap has little or no insulation. Air infiltration is worse that bad insulation. Many of the RV dealers can-do a leak test on your rig with some special equipment. Could be an I'll fittings door or maybe the wall separating the garage from the living area.
