F250 CC SB 4x4 6.2-3.73 or 4.30 for 10,700lb travel trailer

I wasn't aware that the dual disc made the gear rollover noise worse. That definitely makes me rethink the dual disc. I also didn't realize that the posted HP/TQ numbers were at the rear wheels and the clutch you have would certainly be higher than I would ever tune to. I may just end up going the same route you did.

Thank you very much for providing all of the info!
