They are cool to look at. But appear to be not much more than vans. What capacity for food storage, water and propane? What payload? Without that info "RV" is really up in the air.
Coolest motorhome ever (as "RV" includes sailboats, jetskis and ATVs) would be the mid-1970's FMC. A diesel V8/6-speed auto transplant is all this rear engine pusher needs as to vehicle spec. Fully independent suspension, and all the amenities that make for independent living on the road.
Note the roofline, both the shape and how clean it is. And that the A/C system is integral to the coach instead of relying on separate roof units. But be aware that this also cost well more than the average house when new.
