We have a 2009 Duramax crew cab, swb and carry a Northstar Adventurer 8.5, similar to the Larado. We have Firestone air bags, Hellwig Big Wig sway bar, and Rancho 9000 shocks. With the rear tires, 235/16 Michlin TSX at 80 lbs the sway isn't terrible. I am a totally new to this truck camper gig, and I have the Torqlift Topguns tiedowns. I made the mistake of using the tiedowns too loose, and we would develop a sway that was unacceptable. I reread the tightening the Topguns and I found that the mount arms in the outer holes helps too.
