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?

I 'll take slightly better over slightly worse every time.
I'm not sure why some feel the need to go through a lot of mumbo jumbo and tech speak to reach the slightly better conclusion.
The higher ratio will always tow better.
3.31 and 3.55 are pretty close to start with but the higher ratio still performs better when towing. Calculating a performance standard that uses 30" tires is misguided and misleading. Very few are towing RV's with 30+" tires
