My 2018 Sierra with the 5.3 and extra tow does perfectly fine pulling our 35’ 8-9k camper. We towed across several state lines and up in some hills without a single “wish we had more truck.” I would strongly suggest looking at the higher end weight distribution hitches. I have a Hensley Arrow that I picked up used and sway is nonexistent. Sent from my iPhone using Tapatalk
