Go to the Ram site and look at your payload dwith the options on your truck. It's figured with full fuel and 300lbs of passengers. I just swapped my 14 Ram 2500 for the 3500 DRW for the same purpose. You are going to way over on payload. With air bags, you can handle it fine. Lot of people do it. I won't. Your trans and engine are the same as the one ton, just less payload. Again, a lot of people here are doing it.
