Sway problems while carrying larger truck campers with the 2014+ Ram 2500's have been well documented. The very inboard mounted rear coils springs are the culprit. Ram specifies the max. truck camper weight for all their HD trucks. It's telling that Ram recommends some of their 2500's not carry a truck camper at all.
It's my understanding that you can purchase aftermarket air bags for the 2500 that mount *outboard* of the rear coil springs. This more outboard mounting location can reduce sway. Aftermarket airbags that mount inside the coils do little to reduce sway. Lastly, the OEM rear sway bar on a 2014+ Ram 2500 is 1/2 to 1/3 the diameter of the Roadmaster rear sway-bar on our 3500 SRW. It's woefully inadequate for reducing sway with a larger, top-heavy truck camper.
