I'm gonna respond to this because I said earlier that my fullsize pickup would have trouble fitting thru the trails around here.
It would.
And if you're buying a truck to go four wheeling in, one of the things you probably ought to take into consideration is whether it will fit where you want to take it. If you just want something to bolt crap to so you look cool at the mall, or you live out west where you don't have to squeeze through trees every ten feet, then a midsize toyota might not make sense.
