Just make sure that you can't exceed the maximum RPM of the electric motor at the maximum speed of the truck. A double-shafted DC motor should do fine. If you wanted more traction for snow, you could theoretically put in the diff/axles from the front of a 4WD and drive them separately with the EM.

One thing about rear discs--they tend to drag a little more than drums. Probably won't notice it on a gasser, but it has been brought up often on the EVDL.
