i got a 95 sierra.if i take it easy,say drive 55-60mph i get about 17-18.5 mpg's.mods are on my signature and i don't beat on it.i got a new engine in it,so no it's not going hard core wheeling.that's what i got my short box 77 chevy 4wd on 35's. it gets spendy when you start beating on stuff. not that i don't trust mine off road,i have taken it through the woods,is just not for hardcore wheeling.
