Real small motor homes; value?

I think the true Class B's are expensive because all of the components (bath/kitchen/etc) need to fit inside the skin of a cargo van. There's advantages as mentioned above; but in the case of my TALL husband, none of them offered a bed he would fit in. We ended up taking a Transit cargo van and doing a (simplistic) build-out ourselves. Think "steel tent" with room for a small kitchen and a porta potty.... and an almost King-sized bed....LOL!

I should add another benefit of the really small RVs: the ability to drive on roads in National Parks that are size-restricted, like the Going-To-The-Sun Road in Glacier!
