Beautiful truck. Can I have both fenders??
Just kidding.
You obviously like 'Bolts or you wouldn't be here. Why not keep it? You have a place to store it. fix it up and enjoy it. Just because it isn't a 1/2-ton pickup doesn't mean you can't go to shows, cruise-ins, etc. Like the others have said, it's part of your family history and you may regret it down the road if you sell it.
