Don't the RAM 3500s have a AAM 10.5 rear axle that is rated for a little over 10k rating? Also he said he had the factory rear air suspension which is the exact same suspension you get in a DRW if you order it. So basically same rear suspension as a dually with the air and plenty of axle rating rated by the axle mfg. I'd look for some 19.5s.
There is at least one difference, the 3500 DRW set up has and that is 3 full length springs in the spring pack and one half length spring with the factory air system, the SRW has two full length springs and 2 half springs with its air system.
