I've had two. One in a 4WD extended cab with a 4:11 rear end, would pull anything I wanted with no problems but gas mileage wasn't the best. It went to 140K without problems. Current truck is a 2WD shorty, mileage is about 22 MPG in mixed driving. Only has 85K on it, again without any problems. Good engines, I wouldn't hesitate getting another.
