All of the is your truck up to the task concerns aside, I went up 5,000 pounds from my TT to the 5er, it's been an excellent upgrade in all respects. Tows better, easier to hook up, much more responsive turning and backing. I can tell there's more there when taking off and I had to spend a bit more time making sure my brake controller was setup right buts that's the only time I know it.
