Diesel pickups are for chumps

Seems like it'd be easy enough to use this technology in trailers to have an electric power assist on the axle of the trailer. If you're only using it up steep grades, the charge should last longer and allow for a smaller battery pack. I'm sure there are much more cool ways to integrate that system into a bigger trailer like a fifth wheel as well.

Better gas mileage for the tow vehicle, integrated electrical for the living spaces, solar panels on top, lots of possibilities.
