Anyone have a Dakota with a 4.7??

I had a 03 Ram with a 4.7 and it was a great engine. I started having problems once I reached 150,000 miles. I always had regular maintenance done on the truck but it started with hesitation and misfire. Finally I had to replace the headgasket. Once that was fixed there was no problems. Gas mileage was only 13.9 in town and 18 MPG on the interstate. All in all it sereved me well.
