Boondocking Resources - Tips, Tricks, and Information

I know that this question has been asked in other forums. But, can't seem to find any answer. When you are staying overnight in one of the "free" places, like Walmart, Kmart, Cracker Barrel, and a few others, are you able to run your motor home generator? In some parts of the country, in the summer, it is just too hot without AC. Can't run the AC without the generator running.

Thanks
