I found a 91 Allegro at a local dealership in great condition. At least it appears so on the surface. Since my wife and I are newbies at the Motorhome game, I would appreciate some advice and thoughts on this unit. They are asking $9000. What do I need to check out? Since it was a trade in, they are not offering any service records, so i don't know what has been done. i know any used unit is a crap shoot, but what is the general quality of this make and year? The motor is a ford 460 and has 46000 miles on it. what are your thoughts? How doe this unit handle on the road, in the mountains, etc? Should I have it brought in to an independent shop to have the systems inspected?
