What's up everyone!! New to the forum. I purchased a used 2019 1500 Limited with the air suspension. I tow a 26' travel trailer with dry weight of about 6k lbs. When on the interstate, it feels like there's a huge boulder in the truck bed, swaying back and forth. My camper has the weight distribution hitch, as well as the sway control attachment. Its a very uneasy feeling. I've pulled this camper across the country many times with other vehicles including a 2015 Chevy 1500 HC, and it never rode like this does. Any ideas or suggestions? Thanks in advance.
