Attach a few electric motors with a suspension system and some wheels to the trailer hitch of a vehicle to provide a few miles of all-electric range

Nissan leaf consumes about 13.5 kw at 70mph.
Ranger is less aerodynamic, so ~18kw is needed to cruise - that’s our minimum
To be all electric we also need to make it up hills and accelerate, so double it for ~35kw target power.

Aux Equipment

Power Brake pump: 1-200 (or salvage: $40)

What architecture??

Ebike hub motors

Best 1600 for both motors
