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've been towing with the 3.31 rear end since 2012 - coupled with the six speed tranny it's perfect - flat land or mountains makes no difference.

Well not quite apples to apples, your Heartland 2900 weighs in dry at 9,170#, and has a payload of 4,760#, unless you full time likely only use 2,000# of that so towing about 11,170#. That is a big difference to the OP's likely 16,000# 5er. I would go with at least 3.55's or 3.73's.
