The parallel hybrid technology won't help that much, as most RV miles are not city miles. They're highway and freeway miles. City busses are much better candidates for this technology, since they're constantly stopping and going. The constant stopping allows the batteries to capture the brake energy and use it for launch. That's where the busses achieve their efficiency.

What will help a bit is series hybrid technology, like that in the Volt. That is, a smaller engine running at a constant speed feeding electric drive motors (just like in a locomotive). If it works for freight trains, it would work for long distance trucking and RVs.

How much electro-motive technology is GM still privy to?
