Actually the hybrid RV based on a Dodge Sprinter...such as the Winnebago View/Itasca Navion, would be great. The vehicle gets 16-19 mpg anyway and thus is useful for normal driving. RV'ers with plug-in hybrid vehicles could get very useful local travel done while running on the batteries. At least they'd get about 15 to 20 miles of economical use of their batteries! The point is, I think, will there be enough HP to handle freeway speeds at all...right now the View has only 159 on its regular turbo diesel.

Bathroom sink...live with it. It allows cabinet space above and below, a private place to wash up, a place away from the kitchen sink to brush your teeth, etc. One of the ideas of an RV is to have something like a home on wheels and a bath sink fits in and unless you're on a solo drive, nice to have. Some RVs even have two...no THAT's a waste!
