Used pickup markets don't make any sense, that is why 06 lbz duramax's are still going for over $20k in nice shape...
If you're looking at the price range for used, what are new trucks going for? In 17 I could buy a new Ram sport from my buds dealership for $32,500 with the Hemi with rebates and I bought my Tundra for $33,500, but that was a great deal right at the end of August when 18s were rolling on the lot
