Lucky if it can move itself let alone a trailer too. It's an old truck even in perfect shape I wouldn't want one. Those 6.5s were very troublesome.

Not as bad as a 6.0!
But yea unless you like tinkering and fixing all the ill conceived gadgets on the engine, stay away from the 6.5. Now the 93 is better due to the mechanical pump but I wouldn't pay more than a couple grand for one in good shape all around.
They used to make fine commuter trucks back when the only real diesel was in a 20 year old design Dodge and gassers sucked even more fuel than they do now.
Had a '94 6.5 for a while and I loved the 19 mpg on the hi way compared to my gasser trucks.
The 6.5s still seem to bring more $ than their worth IMO to those who want in on having a diesel but don't have much $.
I bought, fixed and flipped/sold a '94 1500 diesel a couple years ago. Truck body etc was in great shape. Made good money on it and the buyer sold it again pretty quick. Probably had more issues, but he was asking more than I did and it wasn't posted long.
