We live in AZ and pretty much can't travel to anything higher in temps than 80'F. Again this year for our summer vacation (because the Mrs. is a teacher) we headed to CO. We also went to central CA but traveling through the desert is really only done in the early mornings. Saying that we have looked into adding a additional AC in the rear of the coach. It is supposed to be wired for a additional AC unit. However as mentioned your coach now needs a 50 amp service. Not to mention a capable generator. It's sad that they (manufactures) can't use some sort of material that can insulate better or have better performing AC units. We did find that some of the ducting was not aligned and they fixed that but it only made a slight difference. One Class A owner we talked to, when it is hot, tapes a home furnace intake filter to a couple of windows and has a water drip system and then turns on the upper ceiling fan to draw in cool air. It would be a nice option until you have to drive.....
