I think you can do better down South. If you lived in CA I'd say otherwise.
Just for comparison, not saying it was a good deal, I saw a 2014 Tradesman with 155k on the lot locally and they were asking $55k. Central CA coast with a lot of cattle ranchers and short on trucks so they may have gotten $50k for it.
On the same lot was the truck in my profile with 29,000 miles for $50k and I was able to swing it for $39k. I purchased it in June. KBB was $45k. Since then I have added a lift pump, exhaust brake and upgraded steering and feel the investment worthwhile for a non- EGR 5.9 in great shape. So I have some $$ in it and would do it again with this truck.
More comparison, on the same lot used trucks have gone up about $5k across the board due to shortage.
More comparison, a nearby owner of a 2014 2500 with 140k just put $12k in repairs. $4k out of pocket for EGR valve and other work, and approximately $6k in transmission that was part of drive train extended warranty from the same dealership. My wife works there so I get these type of comparisons from time to time.
Used or new these are expensive investments with expensive upkeep. Try to get all upkeep records to see the truck's history.
Happy hunting!
