yeah, i dont use 5th much either, unless im on a long trip. i get on the highway in 3rd, and i can keep it there till around 75 if i have to. its actually kinda hard to keep it in 4th on the streets and still do the speed limit, if theres a speed trap, a slow car ahead of me, or anything happens that i have to slow down for, i almost always have to down shift, a lotta turns around where i live i even have to go down to second. im hoping to put axles from an auto(3.55) in too. 3.07's arnt too hot off road either, especialy when ur following someone in mud, and ur trying to keep ur speed/rpm's up, and u have to be carfull to keep your distance. i end up using low range more than my old truck
