I am so glad I kept my 7.3. 240,000 miles. 1 transmission, new ball joints and hub bearings. Next up new tie-rod ends and rotors and calipers. Driving without payments is priceless. The repairs over the last 10 years since payoff are a fraction of the cost of a new truck. I know with the age and mileage things will need replacing but the most expensive is the engine and the 7.3 is still got a lot of life left in it.
Good luck and congratulations on the new truck. If my truck were to need replacing I would purchase the same package that you did. Good value for the price.
