OP said no Dodge, But if you can find a used van Xplorer built in Michigan, they blew the rear walls out and put a rear king in one model that has a dually rear axle. Might be just the thing for boondockin'

That this was one of the 1st models to come to my mind made me think on just how well this unit functions as a B-plus. Even better than my rig, which is decalled 'B-Plus'.
I looked hard at the Xplorer when we were shopping in the early 2000s, but never got to see one.
