details on your truck might help?
4x4 ?
5 lugger?
a tacoma is set up for the highway
the 4x4 and pre-runners have lower gears for off road
you could put on bigger tires,
if 4x4 you could put on billies ( shocks) and a aal in the rear and get more wheel clearance for BIGGER tires can give a 2 1/2 lift
here is a tire chart/gear chart so you can play "what if"
