+1 Keeping up on the maintenance as mentioned is the best way to get high mileage. I knew one guy who admitedly was lax in the maintenance on his RAM and when we were last in touch had close to 200K on the clock. I would not advise his approach, but certainly speeks to the stoutness of these motors.
