I’ve just sold a 30’ toy hauler and am now looking for a used Class B, 19-22’, with a rear or side rear door, under $15,000. This puts me in the late 1980’s and 1990’s vans. Having had the trailer I’m familiar with RV systems, but am a hopeless mechanic and almost all repair work will be done by the professionals. I’ve been looking on-line (primarily Craigslist) at the following: Chinook, TransVan, Born Free, American Cruiser, Travelcraft and Phoenix Cruiser. Like everyone, the higher the mpg the better and I’ve only seen one Class B with a diesel. I’m looking for advice on the relative merits of the above and the various Dodge/Ford/Chevy engines. Thanks for any direction you can give me. Al
