Hello: There is a 1989 Roadtrek with 120,000 miles on it for sale. It looks to be in great shape, no rust etc, everything works. Asking price $8500. I have always wanted a camper van and this may be my first step but I was wondering. If the motor goes, what is a rough estimate to have it rebuilt? I don't want to be negative but it has to go at some time and if it was sooner than later and the body / camper is still in great shape I think why not? It is a dodge van chassis 318 V8 ... if that makes a difference in longevity or points to certain issues with that engine. We will assume the driver was respectable to the vehicle. thanks
