We pull a 2950RK with our F250SD It has a V-10,auto 4WD, short bed,ext cab. with 410 gears. We have not had any pulling (or stopping) problems with this combo. I have hit some hills that has dropped it into a lower gear,but if we are traveling at 60mph we hit the top of the hill at no less than 45mph. I don't know how much heavier yours is but I am comfortable pulling this unit with the 250.
