Hey,

What would a 1992 5 spd ,4 cyl, full rebuilt land cruiser axle, w/ 4,88 gears ,and full Detroit locker, rear out tacoma 98' w/ OEM toyota locker,
4"susp lift and 3" body. 35-12.5 /15 BFG mud terrain...

Be like for a daily driver? Mostly Highway? and mpg guess?

 

That'd be a pretty thirsty beast and probably not great fun with a head wind :p

 

Well, with smaller tires than those, you'd be better off. As is, maybe 16-17mpg on the highway (unloaded) and less in town. Hills will be challenging, too.

 

take off the body lift less wind resistance and it will help. and you will still be able to clear the tires i think...
