Went to look at the 2004 251, it is in great shape, but it is a Ford, and we aren't particular from Fords to Chevys, however son says Chevy's are better and we have a 1979 Chevy20 that has held up remarkably. Is the gas mileage alot different form the Chevy to the Ford?? The unit seems perfect, has the air, the generator, the night/day shades, electric step so alot of the "options" we've seen on the R-Vision site. Is there enough room to store chairs and a table for outside use, a barbeque??? Storage seems alittle small as we want to do a 6 month cross country trip next fall/winter. Another question is if we store the unit for the winter (private paid) would we need to insure it??? At least not to drive just comprehension fees?We have alittle time to think this through, he did say he had taken it to a dealer and would promise him $34,000 for a consignment sale, so I'd assume he wouldn't take less for this home. I was kinda hoping $32,500 would be my offer. Thank you Reno and Charlie for your answers!!!! Karebear
