I'm feeling inadequate with my 1999 Chevy Tahoe 4x4 with 167,000 miles on it. It's gotta leaky rear main but it's slow enough not to worry about too much. I've added Monroe Sensetrack shocks with coil helpers to the rear that helped ass sag quite a bit and do not change the DD ride. It also has load range E Pirelli's on it. It actually pulls really well, I've got no complaint other than brakes which could easily be fixed if I just redid the brakes on the trailer. Until I have the money to do that, I'm getting the rotors turned or replaced every 2 trips or so when I've towed a heavy load (Jeep on Trailer).
On the upside, it's all paid for!!!
