Jimmy is correct for non com operators. It varies state to state for liscense reqs. But as the OP is talking about his business trucks it wouldnt apply as he would be comercial.
I have done the conversion with my 2005 Dodge Ram 2500. I absolutely love it. I pull a Keystone Raptor 3912LEV, in short a very long heavy toy hauler. I first pulled it with the SRW, but did not feel safe. Since I changed out to the DRW I feel confident in the weight capability and handling of the the rig. The change out was not very expensive in comparison to a new truck either. 1200 for the axle, 1200 for the install by a reputable transmission shop, and fender extensions from Wallis fenders (very happy with) 400. Dually STEEL rims 500 (remember your looking to increase weight capability). Try to buy a dually today over the cost of your SRW for 3K.I got a delivery business and I need to improve my trucks because it is booming now. I plan to convert my 2 2019 Ram 3500 into dually trucks to improve their capability in carrying heavy loads. By the way, I'm thinking of purchasing this wheel. What are your thoughts about it?
