Regarding the generator shutting off -- I was told by the dealer I bought mine from that Thor has a feature that if your gas tank gets down to 10% it will shut off the generator. The purpose is to make sure you will have enough gas to to start the vehicle and drive to a place to get more gas. Twice, when I was without shore power, had a low gas tank, and needed electricity to operate the slides, the generator would start and run for about 15 minutes, after which it shut itself off. I was not using AGS.
