32 ft class c a/c in the southern temps.

We carry the material shown above all the time with us - just in case - for extremely cool or hot temperatures. We have it all pre-cut for the windows and store it rolled up and tucked away high in the back of a cabinet.

We toured the Deep South in the U.S. a few years ago in July and August (never again). We didn't have to use the material because most of our camping was in the shade - but what we wish we would have had along was a dehumidifier. The toughest time we had was one night when the outside temps were only in the low 80's, but humidity was as high as possible without it actually raining. We ran the A/C non-stop to remove enough moisture .... but to keep from freezing because the outside temperatures werent' that high, we at the same time ran an electric heater. We balanced the settings just right between the two so the that the interior was maintained at a dry 72 degrees.

I might add however, that in those conditions in that part of the country at that time, we had all the sights and attractions pretty much to ourselves!

Probably helps, but it looks ugly in the windows....lol

Also make sure that your cab dash-air system has it's outside vents closed: On our 2005 Ford chassis Class C, we do this by turning the dash air control knob to OFF with the engine is still running.

We have an ancient (1990) RV. It has a Coleman Roof Air model 6759727. I have no idea how many BTUs it is. Our RV only has an Onan 4000 generator in it and we have a 30 Amp receptacle.

The AC works fine. On very hot days it will run continuously during the day but it is always more pleasant inside than outside. At night it usually runs intermittently.

One trick to reduce thermal load from sunshine is to deploy your awning. This keeps the sun off that side of the RV.

As others have said make sure you put up your privacy screens for the cab and the overhead bunk - this helps keep the cool air in the living space of the RV.

Make sure your vents are closed.

I noticed some mentioning additional steps they are doing to keep their RV's cool. Theonly thing we do is pull the shades down and we use a vinyl windshield cover.

We never have used reflectix or the vent inserts. Our vents do have the darker (black) vent covers on them, perhaps that helps some. If we have the chance to pick shade, we will. But normally, when at places, like the beach, that is diffifcult to do. And at our favorite state park in the mountains, there's not a lot of shade. And it does get it into the 90's there during the summer. Still no problem.

We have never had a problem keeping our 32' Class C with 2 slides cool. Our unit has one 13,500 BTU ducted A/C. There are times when it will seem the A/C runs constantly, but we have never encountered a time when it didn't keep the RV cool.

We've camping in FL and GA in the summer. I think the worse we ever encountered was a 96 degree day in central PA. The campground we were at had no shade at all and we were on the side of a hill. We got sun all day long. The A/C ran from sun up until sun down, but it stayed cool.

We camp in the winter as well. We use thermal curtains to keep the hot and/or cold air in the cab area. The cab over is noticeably cooler on cold days and noticeably warmer on hot days.

Does anyone know how many BTU the Ford cab AC has? On a gut level I think it is very healthy-several times what's available in the roof AC.

On a trip to Tombstone Az, we endured record highs. This was 2010. We have a 30ft Fleetwood Jambo, no slides. My family of three plus a rotty. We have a ducted 13500 ac. We kept the shades down had portable fan running and set the temp at 75. The unit was was able to keep up. We left Tombstone and landed just outside Phoenix. Don't remember the name of the CG, but it was big with a casino nearby. By 1:00 p.m. it was 100 degrees. We were able to keep up barley setting the ac at 80 with fan going. It was comfy. I finally started the v-10 up and maxed the ac. That did the trick. 75 degrees was achieved if not cooler. I did that of and on till sunset. You can idle the Ford for a while won't hurt it. That's my story hope that helps. Good luck. BTW it was 108 by 3:00 p.m.

We have used a small box fan. The air from the fan makes it feel cooler then it is. Like the ceiling fan in our home's bedroom.
