I am in the process of setting up my new-to-me '04 Dodge Dsl Dually to carry my 4200 lb TC that I have carried for 12 years on my '96 Dodge Dsl SRW. I have 19.5s on my SRW.
My changing trucks is for creature comforts, and the DRW came up at the right price. I have had DRW trucks in the past, and have no obsession with them, but will say they typically have less need for suspension upgrades. I do not need 19.5s on my DRW.
What ever you do, I encourage you to go with a diesel (power), and if a SRW, 19.5s (load capacity).
