I just bought a 2014 2500 Tradesman with the chrome package and shift on the fly electric 4 w/d Cummins. It is very well equipped for the lower end. I also have the factory fifth wheel package. However, one issue I did not consider are driving lights. We live in the mountains and I really miss the low side lighting on these sharp mountain curves. For that reason alone I would go SLT if I were do it again. I also use the Sidewinder because that's what I had with my 05 Ram 6.4 bed. I now have a long bed but will stick with the sidewinder. If I don't like the combination I can always remove the wedge and put the bolts back in the turret. Just finished the folding cover today and with the picture frame from eTrailer and my Reese 16K hitch the cover has 2" of clearance.
