I agree, a closer look is needed. The 6.5 diesel N/A & 4 speed dodges the turbodiesel engine issues from 1996-00, however, the big issues with the early trucks is the fragile, generally non serviceable HVAC.
There's holes in the interior/missing buttons and I would guess inoperable CTIS which is common with lower cost trucks.
The exhaust coming out of the passenger side wheel well is interesting... I thought all diesel models had it on the driver side, but this is a model without the AUX tank and I know on some years they mounted the muffler on the rear instead of next to the main fuel tank [Gassers?]
If the wagon top is rust free, then it can be an ok base for a refresh.
