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.




If you just use common sense you can tow in OD with no problems.
I have put tons of miles towing a 34' 16k pound 5th wheel and a 32' 12k pound enclosed race car trailer all over with zero problems out of trans.
Only time you need to take it out of OD is if it starts to shift hunt back and forth.
