I'm new to this and am still learning lots of things. One possible drive configuration I've been thinking about is two front wheels, each independently powered, and a third wheel on a caster at the hitch. I thnk that this could provide better traction and manuveurability than some othe configurations. Balance would be an issue to ensure more weight was on the front wheels. Could anyone please point out things I'm not considering well? Thanks!
