Hybrid Diesel Class A

I would like to see a hybrid motorhome. I don't think it would make any significant difference in terms of fuel usage (aerodynamic improvements would be a far more beneficial course for that), but particularly for an all-electric coach I think it could make sense as you could use the traction battery bank for the house batteries and eliminate the separate genset. If battery power gave one a couple miles of range at low speeds, it would make it more easily possible to arrive late or leave early without unduly disturbing other campers.

A good portion of the Prius's exceptional gas mileage is due to good aerodynamics and low rolling resistance tires. With a conventional drivetrain it would still be one of the most efficient cars in its class, probably class-leading when it first came out.
