2003, 235k miles. "Yeti" has been arguably one of the best TV I've owned. Best with roughly 5000 to 5500 lbs, trailer brakes, WD/Sway combo hitch. I've pushed it with overall and tongue weights, but find 5k to be smooth. Been coast to coast with the current setup.
Things to be aware are the total GVWR, the AHC response, and keeping an eye on the mpg. City I routinely get 12.5 to 13.5 without a trailer, and dipping as low as 7.8 pulling through the smoky mountains. After tweaking a few things (Chevron fuel system cleaner, new manifolds, and maxing tire pressure on both TV and trailer) I just averaged 11.2 from LA to Vegas. Sticking to 60 or so mph, driving in 4th makes even 6% grades very manageable.
It's not uncommon to drop into low (not limp) mode if the overall or tongue weight pushes 700 pounds. Don't sweat it, but I have found stopping, having passengers get out, and pulling on the bumper as it raises to N, it generally stays if you're not way overloaded.
I did adjust the torsion bars and bled and replaced the fluid in all 5 globes on the AHC. I do have the integrated hitch, but also bolted on a frame hitch. I would not use a WD hitch in the bumper hitch and have found it smoother using the bolted on since it distributes the weight.
There's really nothing better than traveling in such style, such capability, and luxury.
Bottom line, awesome!!
