Like Justin said, these kids are driving the price up, I expect diesels by 2020 to be 100K+. MADDOG is also correct about GVW, so a 3500 wouldn't be a bad option, Justin is also correct on the duals being cheaper than the singles. In my personal experience USA for in spot on, the 6.7 doesn't have shit on the 5.9. Do you like that body style or the earlier 3rd Gen? I would say look for a 1 ton DRW or SRW (whichever you prefer) in 04-07.5.
