Anyone changed their rear end for more towing capacity?

Wmoses,

Isn't your TT like 5500 pounds dry? You are likely in the 6500 pound loaded range for a couple's worth of gear.

The TT I am looking at is 6100# dry with a 7550# GCWR.

My trailer payload estimate is based on what I carry in my present RV which is about 3000# dry and 3800# as weighed. That includes some mods, propane, and everything else for a functioning RV.
