Truck: '13 Chevy 2500HD, cc, sb, 4X4, SRW, Dmax, Allison. Stock suspension, but will upgrade to Timbrens, and may look into air bags.
Looking at KZ Durango Gold G359RET: UVW 10640, dry hitch 2190, dry axle 8450, NCC 2960, GVWR 13600.
Hitch is a Reese 20k slider.
I think you'll be just fine with that setup. Probably over GVWR, but within your axle weight ratings. I'm not an expert on GM trucks, but I would bet your truck is identical to a SRW 3500 aside from a softer rear spring pack, which Timbrens or airbags would address (if necessary). I don't think the payload sticker means much on 3/4 ton diesels because the GVWR is restricted by class, but tire and axle ratings are important.
