I am looking at getting something used in the 15k price range maybe up to 18 or 19k. It needs to last a long time. I'd prefer stick and 4x4. I was thinking a RAM 2500 diesel. I wanted to get y'all's opinions on that truck or any other that are in the same class that I might want to look at. Reliability is longevity are going to be the 2 biggest factors here. Any experiance, opinions, or recomendation are appriciated.
