I've never avoided a campground to save the cost, or stayed at a Cracker Barrel, Waltmart, etc... not that there is anything wrong with that as far as I'm concerned. On the other hand there are numerous reasons we might want to spend the night where shore power is not available. And we do occasionally -- not often but it happens. I like the option.
For that reason being able to run the AC at night without plugging in is a big plus. And because of safety, noise, vibration, and Natural Park restrictions, I would very much like to run it off batteries instead off an internal combustion engine. For a Class A that may still not be practical/affordable, but I look forward to the day it is. For a Class B I would definitely pursue it at present level of technology.
