Had a '09 Dodge diesel, one ton, SRW,auto, 4X4, long bed that we bought new. Put about 97K miles on it, with about 30K of that towing our 35' 5th wheel. The power train was very good, but if I listed all that went wrong with the truck, it would sound like a rant. All service, & repairs done by the dealer. In May of '16 traded it in on a new Ford, 6.7, SRW, 4X4, long bed. Only have about 14K on the Ford so far, 6K towing, with no issues. Just checked the inventory of the Ford dealer, & they are still sitting on my Dodge since May.
