I want to build a solar/hybrid pickup, attaching the electric motor between the tranny and the rear end. My first question is, can the gas motor and the electric motor be used at the same time? The gas for getting going, and the electric for just cruising? I'll need recommendations for the smartest combos of truck/electric motor, with the easiest marriage of the electric motor to the drive train. I have no problem making driveshafts, done that.
