on which tranny? If its a half ton chevy with auto then no OD when towing or offroad. If its in overdrive it will constantly switch between 3rd and OD causing things to overheat. Other than that I just leave it in OD and let it figure out what to do.

no load or possibly flat road loaded= OD
loaded = D
