I have an 08 Yukon xl (5.3) 2wd w/ 3.73's. I added a leveling kit, rear spacers, and 285's. I just bought a travel trailer weighing about 6000 lbs loaded and am wondering if it would be beneficial to add 4.10's or possible 4.56's. We went to the lake this weekend and any incline at all the motor has to really work and the transmission has to downshift. I used to tow with an 05 Cummins and know this will never be close as far as towing power but I need the room of the xl. As it is right now any trip to the NC mountains is out of the question. I hate to regear and spend a few hundred dollars if I would barely be able to tell a difference. Any advice?? (short of buying another diesel)

I have also heard exhaust systems help torque, and some hurt. I have thought about exhaust but definite NO if it will hurt performance.
