Need Opinions- 2002 Dodge Ram 2500 CTD

If the trany felt slugish, I would get it checked out, that truck should not care if the bed was full of snow and ice. $19.000 is way over priced. I bought a 2002 2500 4x4 diesel 6spd 102,000 on the clock for $15,000. A good lift pump is a must as is a fuel pres gauge.
