Winnebago ac

[gp44]

My new Adventurer 37 seems to have an ac problem. On a 95 degree day, coach was at 84 inside. Closed all blinds and turned ac to 70. Ran at full blast for 3.5 to 4 hours and temp dropped to 83/82. Also was getting good air flow from all outlets except the one in the bedroom. Service rep at dealer told me that this was; 1 a design flaw from Winnebago, 2 too hot outside to fully cool the inside, 3 because we bought a dark color and absorbed more heat. In all cases, he could do nothing.
Is this normal or semi-normal? Everything I read on these forums indicates the Tru air ac on a Winnebago was outstanding and worked very well. If 80 is the best I can hope for on a hot afternoon, this will severely limit my usage.
Any advice, comments or suggestions will be welcome. I bought the coach but have not taken it off the dealers lot yet.
Thanks

Wow! That does not seem to be a normal situation to me. The air coming out of those vents should be down around the 50 degree mark, and it does not matter what the temperature is outside. It may not cool it down inside if it is very hot outside, but that vent temp should still be pretty darn low.

I live on the Gulf Coast of Texas, and it gets pretty darn warm down there in July-August, for sure. With temperatures in the high 90's I can keep it down low enough to be very comfortable. I run off of 50 amp at the house and most CG's. I do know that if I'm running off of 30 amp or less, that one of the compressors will not kick on due to the Electrical Management System. That could cause it to be a little warmer than normal.

I had the same thing told to me about my Dash AC, that it was to hot outside for the dash air to be blowing more than 15 degrees below the outside temperature. That is a bunch of you know what. I have never been in a vehicle that did not blow between 45-55 degree air out of the dash vent, on the hottest of days.

Don't leave there until it is cooling down to a comfortable level. (80 degrees is not comfortable)

Thanks for the feedback. I live in the Austin area myself. I agree with you and will not take it off the lot until it is fixed. I am now working with the service manager and maybe I can get something done. At least he agrees that something is wrong and promises he will get it fixed. This is my first mh and wanted to make sure I should expect the ac to work better that it has so far.

Sounds like a Freon deficiency. Get a refrigeration thermometer. They have a round dial on a shaft (~1/8"). The temp coming from the vent should be about 20° lower than the inlet temp.

In any event, have the seller check the AC out.

Many people that have your complaint have found that there is an air leak in the ducting from the AC top of the coach. Apparently there are some joints that can either slip or become open in some way. This is a fairly common complaint for some model years.

Also, if your model has the dual compressor A/C you might want to make sure that both compressors are running. The temp drop of 20 degrees is pretty much optimum for a home unit but I don't know if it applies to a dash air unit. My car will put out 35-40 degree air on a hot day when it comes on.
