Any suggestions on keeping the coach cool for passengers during the summer other than keeping the engine A/C fan on high and running the generator to use the roof unit?
You do realize that running the dash air uses far more fuel than the gen with AC on. That's one of the reasons we got a MH. So the family can relax in comfort. Central air, TV, cold drinks etc. Why wouldn't you run the AC? That’s what the gen is for. Are you trying to save fuel or something? It might be .5 mpg at the most.
