We have had our pickup since it was brand new. It as nearly 165,000 miles on it and still runs great. I have had no major problems with it. The only things I've had to replace is the battery and the brakes. I put my first set up brake pads on when it had 150,000 miles on it. I would stick with the Hemi. Gas mileage isn't great, but you would expect that with a pickup. I average about 17 MPG. Its a comfortable ride and has lots of power. It also has good visibility and is fun to drive.
