Well around here ( Ohio valley area) more than likely all your weight is goin on the front... Whether its a diesel truck or an alcohol/gas truck... Around here is the best dirt in the country.. Iv never saw a dedicated gas pullin truck (pro stock) put any weights in the bed/rear. And it doesn't matter whether your truck levels out or nose dives the whole way down the track.. Weight transfer happens all the same in either situation.. Of course it looks better if its level personally but it jus doesn't matter.. If u wanna have a good set up block rear and block front, keep front axle level.. Keep hitch height at max, when u take off u don't want the front to raise at all... That drops the rear down( lowers hitch height) and your basically unloading the rear( less pull down from sled).. Schew.... Done
