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?

Nobody is speaking about tow haul & heavy loads. My 2020 GM 10 speed has almost identical gear ratios in every gear to Ford . Although I have no Ford manual to read ,my GM manual claims that it will not go beyond 7th gear in tow haul. I would expect Ford the same. One thing I know for sure they all blow the doors off semis in the mountains pulling 20,000 lb. load.
