AC in an RV: we had a 27 ft with a big A/C unit. It kept us cool, even when staying in Phoenix in the middle of the summer. I was less enamored with the furnace in ours, which wasn't nearly as efficient as the A/C. The vast majority of RV's have Coleman A/C units, and they do make a good one. In the 14 years that we had our rig, it only had to be serviced once for a problem. Longer rigs, btw, usually have two A/C units. That said, they also have a 50-amp cord. Also, common sense tells you, if you're on a generator, you're probably not running an A/C unit. :-)
