A heavy vehicle is not something one should have ANY expectations of getting any respectable MPG out of. It takes torque to get the thing to move and to keep it going....easily. Put a high gear in it, like a 3.00:1 and you'll be lugging the engine all the time. Not a good thing. I have had heavy cars and pickups. Any engine/gear selections will all be made on the power side of things, not MPG side. Easier to drive, and more fun to drive.
12 is actually pretty good MPG!!! I would NOT change the gear ratio!!! the MPG difference will disappoint you. I'm with you on the posi idea. Been in situations where 2 wheels spinning would have made a difference.
