For those of you with the 6.7 Ford diesel in your F350, did you go with 3.73 or 4.30 rear axle? Do you still like that choice? I am looking at larger/heavier truck campers (4000 lb or more dry) and a approx 3000 lb boat with about 1000 lb of propane, equipment, water etc.. What is your experience?

I am looking at larger/heavier truck campers (4000 lb or more dry) and a approx 3000 lb boat with about 1000 lb of propane, equipment, water etc.. What is your experience? ..I have the second generation 6.7 (2016) in an F-450....The engine is so powerful and has great low end torque you could get away with more of a hiway gear (3.73)....Mine came equipped with the 4.30 rear as it is a purpose built truck from Ford designed for hauling / towing....I believe max ratings are around 32 or 33,000 lb total vehicle weights (truck and trailer).....I do have a couple of RV's....a large truck camper which pushes the truck up to its max gross weight (14,000 lbs).....and a 34' travel trailer that we use for extended stays....the trailer weighs in at just over 10,000 lbs....with 1300 lb tongue weight....I do NOT haul these it the same time.....as there is no real safe hitch extension that I would trust (no not even the super truss).....But with the 6.7 and the lower dif....the truck never seems to work hard.....or get hot....never had a hill that needed more than one gear down shift.....and consistently get in the low to mid teens milage when loaded....feel a little juvenile ?..Punch it ....truck alone....you could burn the duals off !....For me and any one doing a heavy haul.....go with the lower dif ratio.....if your off time you do a lot of hiway miles (unloaded)....the 3.73 will help keep your heart rate down at the fuel pump.. |
