Sway Issues with 2013 1500 Suburban
I'm having sway issues with a recently purchased 2013 Suburban LT 2wd w/8100# tow package (K5L) towing a 2000 26' Coachman w/ scale weight of 6000 lbs. Side winds and trucks are now a pain in the boat. Got about 600 lbs tongue weight with a 1000 lb Equalizer.
Scale weights are front 3120, rear 3340 and trailer 5440. Burb alone 5900 lbs. Hooked up, front end within 1/4 inch, rear end drops 1 inch and the bars and trailer are level. I've towed this same trailer about 20,000 miles with a 2004 Tahoe and a 2005 1500 Suburban(with Bilsteins) without any problems. RPO code indicates ZW7 premium smooth ride, but it does not have the nivomat shocks. When a dealer looks up the part number via VIN, it does not call for the special nivomat shock, just an $80 shock. Been trying to find out if GM added the ZW7 code without the special shocks, but not much luck with dealers or GM customer service. Also, the nivomat system uses a weaker rear spring. I can't seem to get past the VIN parts listed for the vehicle. Bottom line, I want to resolve the sway issue, but not quite sure where to go from here. I'm used to towing with a fairly light touch on the wheel and I'm not enjoying the tow since trading vehicles.
