Abe, I have pulled a 25' Safari through the Colorado mountains with a Chevy Silverado 5.3L V8 with 3:73 rear and it did okay but not great. A coworker has the same truck and he does not tow but had to have the transmission rebuilt at 80k miles. The dealer told him that was normal.? I traded mine at 50k miles and had no problems other than the rear end getting very hot when towing in the mountains.
