"Tiny houses" take that inefficiency up a notch. Using materials and designs with no regard for road weight.

tiny houses are not typically expected to move around often. the wheels are generally a formality to get round certain zoning rules. that you can move them is a side benefit.

RV's are even less-efficient / less effective tiny houses.

Put another way: the constraints imposed by adding mobility to an otherwise static design are significant, and the inherent compromises large.
