"So I have a 2016 Ram 2500 Megacab with the 6.7 Cummins. I love it. Great truck. It has plenty of tow capacity for us and our current trailer and possible future 5th Wheel upgrade at 16,936lbs."
I am taking this to say, the tow capacity of the OPs truck is 16,936, not the weight of the FW he is considering. A srw 3500 would struggle with a 17K FW. OPs truck may run out of tire capacity as the FW nears 14-15K.

We swapped over to 19.5s on our '15 SRW 2500 for this.
For a while, we also ran Method MR305 NV wheels rated for 4500#/ea, with Cooper STT Pro tires rated for 4080#/ea, which were notably less stable than the 19.5s.
We ran a full Kelderman air ride on that truck, which is the same suspension whether you have a 2500 or 3500.
We bought a DRW when we decided to go FT, and found it notably more stable (with OE LRE tires) than the SRW with 19.5s.
... Now we have a heavy truck camper and 19.5s on the DRW...
With our HO/AISIN model, at least, there are a lot of differences between the 2500 and 3500. The entire driveline (aside from the front axle, I think) is different. Rear axle is definitely different with a much larger tube. Rear brakes are much larger. Transmission (obviously), transfer case, and rear differential are different. HO differences aside, the suspension on the 2500s and 3500s is a lot more different on Ram than it is on the other brands.
