Currently have a 15 GMC 6.0. For some reason I now have the itch for a 3500 SRW. I have always been mostly GM but have had Ford's in a business setting. One thing I have been noticing is, and this is just from advertised prices on the net, is a Ford F350 in Lariat trim can be had at a substantially lower price than a GM2500. And that's in gas or diesel flavor take your pick. I believe I could go F350 dually for less than GM 2500 or 3500 SRW. if I wanted dually. The next TV may very well be an F350 SRW in Lariat flavor with the 6.7
I believe if I was buying, and buying GM, I would hold out for the 2020 total redesign.
