We have a 2021 Suburban with a 6.2, no air ride just magnetic and no max tow. We pull a Grand Design 22' MLE with a slide. It is approx. 5,270 lbs as delivered and probably 5,500-6,000 lbs. loaded. I use a weight distributing hitch and it pulls like a dream. I used to pull with a 2018 Colorado Crew Cab with a 3.6 and 8 speed. It did okay but this is quite a bit better. I might raise the hitch a little to get things a little more level but I am truly impressed with the job it does right now.
