how often do you tow your trailer?
If you use it every day for work, Kyle might be right, another platform might work better for you.
I tow an 18ft bass boat that I would guess is around 3k wet and even with the 32's on 3.42s it does pretty well.
It doesn't do as well as my Suburban with 3.73s but I can pass slow traffic on a 2 lane when needed.
I live in flat country though, and likely only tow 4-6 times per month in the warmer months (March-Oct).
If I was towing it every day, I might look at something more suitable but it works for what I need.
I have 4.10 axles ready to go in pretty soon. I can't decide if I want to put them in during Christmas break(PTO) or wait until after deer season(Jan 1).
