2011 Ram 3500 SRW 5th wheel capability?
I have an excellent condition 2011 SRW 3500 megacab looking to tow 15.5--16.5K 5th wheel toy hauler (2300-2700lb pin). I will be using the toy hauler 4-6 times a year 200-1000 mile trips. The tru...

Even though the 2013 RAM 2500 has the older frame on it, it did receive the heavily revised cooling setup which could explain some of the gain in towing capacity. This along with an extra 20 hp and maintaining the same 800 ft-lbs of torque. So it's probably a cooling capacity and hp increase that made them feel a little more comfy with increasing the tow capacity?
So by your logic, it's a simple intercooler, radiator, trans cooler, and whatever other cooler upgrade along with upping the HP a bit. Maybe also something to do with emissions tuning since the 2013+ motor doesn't have to use nearly as much EGR (so I guess this would be the delete part). I know the pre 2013 motors required maintenance of the EGR valve where as the current motor doesn't have an EGR PM procedure. I also believe that the wheels were pushed up to 18" tires which allowed for the spec'ing of tires that can stand 3600 lbs a piece. Those are all the differences I can honestly think of (aside from the interior which has nothing to do with tow capacity really).
