Bought my 02 4wd with 50k miles & drove it for another 100k. Great
truck that could get 20mpg on the highway & towed like a dream.
Here's some advice I learned the hard (expensive), way:
1. Don't tow in overdrive & you can, upgrade your trans for towing.
2. Don't use a first gen Edge EZ controller. After 3 yrs, mine shorted
out the PCM which took out the ECM, the injection pump & the lift pump.
Dodge employee cost was $7k to fix, so I sold it & built this...
(maybe one day, it'll get a cummins)
3. As others advised, weak link is the lift pump, so do some research
& upgrade to one of the good systems that are out there.
Oil changes are expensive & brake jobs, too, but the Cummins will outlast just about anything if well maintained.
