You know guys... not sure why iam so concerned with going to a srw... on a pipe job today figured id check payload capacity of my 07 5.9, yep! 4705lb payload and 15,750 max tow so iam already pushing the hell out of this dually. When were pulling camper/boat we MIGHT be within that max tow number as boat is rolling resistance. But as for payload.... lol. I have my tool boxes with maybe 250lbs of tools, 60 gallons in slip tank, oxy/acet bottles, 900lb welder, andersen hitch if that even counts at 30lb, and of course a 1000lb welding bed. I have air bags so she sits level, and truck still handles rig perfectly fine. But 2017 and up srws certainly “as a rule” have more payload and towing capacity than i currently have, and garunteed better braking. Only thing they wouldnt have is stability lf dually
In reality ive towed alot more than our camper/boat on our 40ft gooseneck.
