Another interesting concept is the Chevy Volt. You can go about 35 miles on a full electric charge, and then the engine automatically starts and runs a generator to power the electric motors. Overnight charging on a 120V circuit will get you to a full charge, but the generator/engine concept make the vehicle much more practical. My brother bought one recently and is getting about 40 MPG on the gas engine alone. That's not as good as a Prius or some other high mileage cars, but the vast majority of his driving is in electric mode. The electric fuel works out to about 1/4 the cost of gasoline.
Of course, this is not practical for most RV'ers, but it seems to offer some promise for regular city dwellers, giving them an electric car for running around town yet a fuel efficient vehicle for those times they want to travel longer distances.
I realize there is a lot more to the overall cost of ownership than just the electricity to recharge the batteries. Things like battery replacement and tax dollars being used for development, etc., but all in all I think it is an interesting concept that offers some potential benefit. Time will tell.
