Rather than gears, I'd run 235/75 -15 street tires on the stock gears. Weight reduction is the order of the day for mpg, so I'd keep the spare and back seat in the garage and carry some fix a flat.


83 mitsu flat bed 2.6l weber, 88 auto tranny, 2" body lift, 4.625 LSD, 235/85-16E mudders (33 x 9.50).
