Ford super duty 3.31 rear end. Will it be a big mistake. ?
Pulling a 37 foot Cedar creek with a f350. Diesel. Would the 3.31 rear end work or should I get the 3.55?

If buying the truck for towing get the 3.55. Why not? All things equal the 3.55 will perform better towing. The only advantage I see for the 3.31 is MPG's.
A F-350 will never be a commuter car it will always be a fuel hog regardless of the gearing.
Fuel Hog, not to me.
My18 F350 DRW with 4:10 get around 17 empty and 9.5 towing my Cardinal 3350 @ 65 mph. I would bet the new 10 speed will be better than that.
