We have been researching and dreaming of owning an RV for about 3 years. Never thought we'd be prevost owners but we bought a 1996 XL45 Le Mirage last week. Bill has a lot of experience with detroit engines, so I was comfortable with the decision to complete the transaction, even though the seller knew nothing about the operation of any of the systems. (long story) The interior is beautiful and the price was right for us. We drove her the 500 miles home and Bill said she drove like a dream. We are figuring things out little by little and still thinking we can do this! The first question we have is-- can the roof ACs run off the engine as we go down the road, without running the generator? Any information, advice, help, is welcome!
