Has anybody had any problems keeping their Diesel Bounder cool inside? I have a 2007 38V.
It was 104 in Las Vegas, had my shades down bubble screen in the front window, and no body was going in and out.When it was 104 outside it was 89 inside. Temperature drop across the A/C was 19 to 20 degrees(inlet versus outlet).Sun was on the full side. Any suggestions?

Go shopping or to a casino.... actually if I have to be in it and I do all the time, I turn on the generator and run both airs. Even then it's only cool if your very near an air outlet.

Your AC is working properly. A 20 degree drop is all that your AC is designed to do.
If you want cooler, try a trip to Alaska in the summer and go to Los Wages in the winter! LOL

If you are running a 20 dF split across the evaporator with the fan on high speed, it is working for all it is worth. Do you have both A/C's operating?

At 104 dF outside and in full sun, you may not get it much below 85 dF inside.

The best help would be to get into a shade for the coach.

DO you know what size A/C unit(s) you have?

I have exactly the same motorhome except it is the Expedition version. I too had concern in Vegas for exactly the same reason, especially with the temps went north of a 100. That was until I went to my buddies motorhome for dinner. He had a Monaco which was for argument purpose, about the same size. His air conditioning was no better and no worse. I stopped worrying about it after that. You can always put a fan in the 38V. That does seem to help.

Cat,
Your unit is working normally and very hard to maintain a livable temp inside the camper under those conditions. My DW and I were camping out in the open with outside temps over 100 and Betty was very concerned with the inside temps until we went for a long walk. After our return, Betty enjoyed the relief of the 20 degree split.

Poor guy next to us lost his forward ac and had to leave because he could not get the inside of his unit below 95.

Cat,
I have a 2008 Expedition 38F. Very simular coach. We are usually in south and central Florida during the summer months and I have found to drop the coach to about 70 during the night and then late morning open the vents directly on your air conditioner sometime in the morning. Only my front air has that ability but I get more air flow in the coach. I also found that the air filtetrs get dirty very quick and pull those out and clean them off. The air flow will increase tons. Even after that, it will get up to about 82 by late afternoon. Not too bad.

A/C size are 15000.
I am wondering if window awnings would help and a windshield cover that goes over the outside of the windshield( instead of the inside of the wwindshield like I have now), and how much would they help?
I used an infared gun to find out the temperature of the outside of the slide wall(painted side) it was 160f degrees and the motorhome is a sand/tan paint color.Just think how hot it would be if it was black.

Or should I just try to get an "window" size awning (instead of a full 10 foot wide awning ) that cover the whole left side slide? Anybody ever done that?

A Bounder-owning friend turned us on to this idea. We have exterior shades on our windows, but when it is really hot, we place the silver bubble insulation on the outside between the exterior shade and the windshield. That stops the heat from coming thru the glass. It all helps in really high temp places. Good luck, HarveyP

A lot! We are sitting in a park north of Phoenix, temp 90+. Step 1, drawing the shades (duh!) makes a difference, obviously. Step 2, rolling out the patio awning, makes another big difference by keeping the sun from hitting the shades. And yes, the outside screens over the windshield and first side windows make another difference, reducing the heat hitting the front drapes. I never thought of adding insulation under them, great idea.

I am constantly amazed at how many newer coaches I see without window awnings. They do so much to help hold down the interior temp, plus the privacy factor is very nice. Shades/drapes, then awnings = double insulation. What more is there to say?
