They are a decent ride around engine in a Dakota, Durango or Jeep....but I wouldn't want to have to try to tow a car trailer with one. I bought my wife a 4 door Dakota with a blown 4.7 last year, and replaced it with a remanufactured 4.7 from Powertrain Engines. They have the best warranty, and fix all the problems the 4.7's originally had. I'm very pleased with the engine in her truck. It was $2799.00 if I remember correctly. I had to send my old engine back as a core. I pulled the heads off of it and got it unstuck to check the cylinder walls before sending it. It wasn't cracked anywhere, so I didn't have to pay the core fee or shipping. I would buy from them again. Good luck
