but from what I read of your posts you are quite capable.
Use the S-10 frame as the platform. It's fairly light--for a pickup truck and the full frame wil aid in battery install. Use an electric motor to drive the truck. Use a bio diesel generator either on a trailer or portable in the bed for longer trips.
The S-10 has a lot of aftermarket stuff available to lower it--springs, drop spindles, etc., replacement parts are readily available, and since you already have it I know you have already thought of aero mods.
