Issue is the truck needs the same rust repair, needs front doors, passenger rocker, and both bed sides. But you are correct I love the truck.As far as value goes, I think that is a good ballpark trade as long as there is not a lot of hidden rust on the Satty...... but it still seems to me that you are trading down. You don't even like the color or interior and it needs a lot expensive and labor intensive work.
That is a good looking truck. I'd be spiffing the truck up and cruizing it that rather than trading into a major project. If it was me, I would save my pennies, enjoy the truck, and buy something that isnt rusty down the line.
