I am looking into purchasing a 2015 GMC Sierra SRW 3500HD 4WD Double Cab Long Box 6.0L gas. Question - Will this vehicle easily carry a Lance 1121 w/Slide without other suspension modifications? The Lance is identified as having a dry weight of 3260lbs so I am assuming I could be on the road at 4000lbs loaded with two persons. The truck comes with Michelin 'E' tires rated at 3520lbs/tire at 80lbs pressure and 51mm twin tube Rancho shocks and 33mm front stabilizer bar. The GVWR is 11,000lbs and the front GAWR is 4800lbs and the rear GAWR is 7050lbs. The payload for the above vehicle is listed as 4300lbs. Any guidance is appreciated here. thanks

figure on between 7500 and 8000 on the rear axle loaded up. you will need better tires if not an upgrade to 19.5 wheels and tires in the long run

Either 19.5's or get a DRW.If you do a google search on Lance 1121, then click 'images', you'll see they're all on dually's.

We have our 1121 on a 2006 RAM 3500 diesel with DRW (and the camper package). Our GVW is 12000#. I'd hesitate putting it on a truck with SWR. Your truck itself wouldn't have a problem, but the tires might. Peter

I have a 2015 GMC 3500 SRW 4x4 SB. We carry a 2015 855S and are overloaded. Recently upsized tires one size so we are least "about" even with our load. We have the same rear axle capacity you do. 6.0 gas engine is fine but I think you would be better off getting a DRW truck or a smaller camper! The camper will weight much more than the Mfg says it will unless you have an actual weight from previous owners. Recommend checking out Lance Owners of America forum for more info. from similar camper owners.

It will carry it, but you may not be happy with how it carries it. I think most of the people here are over.
