I don't think there is really a wrong answer to any of the questions. Any of the available 1 ton SRW's would manage that weight just fine. If you would prefer a DRW that obviously would make sense as well. I use my 3500 SRW for business as well as pulling my TH so the long box makes the most sense for me. If I wasn't working out of it, I would probably be in a 6.5 box. My '18 3500 SRW weighs 30K combined routinely moving equipment, and it manages the weight well. The newer models have more capacity than this truck does. So you weigh the pros and cons of DRW and decide for yourself. Everyone's priorities are different. Good problem to have though.
