Ithas always been warmed up and cooled down before and after driving.The cab corners are perfect and the doorsand seams are mint. The bed was removed and the entirebottom of the truck andframe was done in POR15. This truck has been babied and the plan was to keep her forever.I have had a sudden change of plans andam currentlyat Marine boot camp. The interior is in excellent shape with the usual damage on the drivers lower cushion. The steering wheel has some wear at the top but nothing too bad. Rugs and matts are in excellent shape as well as the rest of the seats. Over all the interior is excellent.

This truck has been maintained with the absolute best care. When the oil was changed the fill tube would be removed and insert funnel directly into motor

The truck averages about 22-23 mpg The tank has never been below 1/4( recommended by FASS to eliminate strain on the pump due to the fuel pick up line not going to the bottom of the tank.


As you can see there has been an absurd amount of money spent on this truckover the past few years and much spent recently using all the best parts.I have owned this truckfor almost 4 years. The original owner was an older gentleman who babied this truck as well. Although there are a ton of performance adds I never beat or raced this truck. I wanted it to last a lifetime. I have mad a recent change in life and am now away at Marine training. I will not be able to use this truck for a few years and I do not have storage for it. This truck runs and drives like new.
