i have a 2019 375RES. over on the GVRW by a shade and the pin weight is 4200. I did have a 2018 ram 2500 CC Cummins 4x4 w/3.42 gears and air bags and b+w slider hitch. It pulled fine for me. Although I did not like the fact there was zero margin for safety. The factory provided me with a document that stated 4200 lbs vertical tongue weight.
I did trade it in on a 2018 Ram 3500 CC DRW Cummins 4x4 long bed with 8'bed and 3.73 gears. A lot more capacity, and a lot more truck for only 2k more in price (end of year sale and beat the dealership up real good on price and trade value).
The benefits are dual rear wheels, a blow out will let you stop under control where a SRW would be a white knuckle ride.
The dually gets you 935 torque and 385 hp, a lot more engine, trust me.
Integrated trailer braking and engine exhaust brake. It works wonders.
Nearly 9k payload capacity from a truck with a 14kGVRW.
