I traded on a 2005 Pleasure-way Plateau at 61,000 miles and doing the same with our 2011 Great West Van Legend at 65,000 miles but not because of the mileage. Both were in excellent shape and mileage was not the reason. My reasons are my changing desires and quest for newer designs to try. If I could have remodeled my Bs for what I was seeking I would have done so. In some respects the 60,000 mile mark was a sad goodbye because those diesel engines were improving.
