If you decide to need a generator since you have no AC at all, rig one up on rear bumper and run a power cord to your power port. Run the house ac off the generator. On craigs list locally there are 'new' AC units pretty cheap, so you could add one fairly easy. Had one on the slide in camper we used to have again would need to wire it in but its not that difficult. We were at a rest area in the south when a guy pulled in with his TT, had the gen running so they could go into a COOL trailer when they stopped. Rigged one up on the TT we had but never had to use. Just food for thought.
