If by "one ton" you mean a K-3500 with single rear wheels (SRW), then that's reasonable. Ford F-250 and F-350 SRW have the same chassis but with a slightly heavier duty rear axle (differential) in the F-350 SRW. The discontinued Excursion SUV was basically an F-250 with a different body bolted on. So it wouldn't surprise me if GM didn't do the same thing.
BTW, my definition of "one ton" means if it's not a dually, it's not a one ton truck. A K-3500 SRW and F-350 SRW are glorified HD three-quarter ton trucks, not one tons.
Grumpy ole man with over 50 years towing experience. Now my heaviest trailer is a 7,000-pound enclosed cargo trailer, RV is a 5,600 pound Skyline Nomad Joey 196S, and my tow vehicle is a 2012 F-150 EcoBoost SuperCrew.
