I have a 2014 Tahoe with the tow package. It has 157k miles on it. I just installed new Gabriel HD shocks (coil overs) on the rear. I purchased a Keystone trailer with a dry weight of 5400 lbs thinking the Tahoe could easily handle towing it because the book says max tow capacity is 8200 lbs. I have the proper sway bars and hitch set up, but it still gets uncomfortable (sway) at 45-50 mph. New tires are on the trailer. The hitch drops approx 2.5 inches when hooked up, so I believe I have enough tongue weight. The sway bars are tight. They pull the hitch up approx 1.5 inch. The drop without the sway bars is 4 inches. The drop with the is 2.5 inches. I'm not sure what to try next.
Whenever you change parts and then have a problem, the best and first thing to do is un-change them, put the old shocks back on or buy a set of ACDelco factory shocks and try again.
As for the sway, need more weight on the tongue. The tail is wagging the dog. Load up the rig like you were going on vacation and take it to your local CAT Scales. Download the app so you don't have to go inside and get the ticket unless you want to. Weigh the truck by itself and then again with the trailer with each axle sitting on the right scale, steer, drive and trailer. You want about 13-15% of the trailer's weight on the tongue or axle of your car, your hitch can handle 1100 pounds easy, your payload capacity for the truck ought to be north of 1400 pounds.
if you want to get really precise, put the trailer on the scales by itself, with the jack on the steer axle, front axle on the drive and rear axle on the trailer and take a measurement. First weigh now is $13.50 and re weigh is $4.
