Purchased truck in high school, drove through college, now married and still running. Truck is amazing in all weather. Only minor problems over 110,000 miles, including the standard crap Dodge transmission. I mostly drive unloaded but tow cars probably 1500-2000 miles/yr and it works great. Can't wait to get some money to put some performance stuff in her. I get great mileage, 20 mpg with the 5.2L on straight highway miles, 16-17 on normal driving. Little tip...Firestone Destination LE tires are amazing on this truck.
All things considered not a bad truck in a 140k miles. Bought used with 30k miles and 2k later transmission went and was repaired under waranty - no problems since. Have the 5.2l V8 with positraction. Used the truck for hauling a 4500lb boat just about every good weather weekend and commuting to work. Replaced dist pickup at 65k and 120K, O2 sensor at 120k due to a "21"error code, and blower resistor at 110k. Aside from normal wear items such as tires, brakes, plugs, fan belt, radiator hoses etc. no other problems - very reliable. Been using Mobil 1 at 7.5k oil changes and does not leak a drop of engine or tranny oil. As with all these dakotas, the headliner fails, and fuel gauge is whacky.
Owned the truck 6 months, first dodge I ever bought. My dad talked me into buying it. I learned 2 things from this truck. 1. I will never buy a dodge and 2. when the check engine light comes on, it's junk. Get rid of it. I have put more money into this truck than i did my 300.00 1988 ranger that has 300,000 Miles. I really do hate this truck.
