Will Single A/C cut it?

We have been in a 37 foot toy hauler fiver (Keystone Fuzion) for 3 years. Most of the trips we take are extremely hot weather - over 100 degrees. Our toy hauler has two 15k A/C units and can't get more than 20 degrees under ambient. When it is 110 outside it is miserable inside.

We are looking at class A RVs now and would rather have one in the 29-31 foot range but those only offer single 13k A/C and 30 amp service. It seems to be around 33 feet where the manufacturers offer dual A/C with 50 amp service. I don't have room to park a 35 footer and a cargo trailer I will need for the toys with a class A.

My question is this - - do the 30 foot class A RVs cool well enough with only one small A/C unit?? I hate to spend 90 grand and still be hot.

BTW - we are looking at Fleetwood, Winnebago and one Jayco. Any comments are welcome good or bad.

Thanks

Many have added a third unit to the larger ones and ours with two, has a hard time getting the temp. down after a day on the road in extreme heat, but the real problem with having only one, is for when it goes down and you now have nothing until it's fixed or replaced.
