Most people don't want a 1ton due to the heavy suspension & length. Personally, I think those are must have attributes. I'd give up a kidney for that truck! I really like the grill guard.
Value: for your low mileage, rare truck with a little rust; I think you can get at least $3000 for it. Put it in the swap meet section & on ebay.
I'd hate to see you regretting selling it a couple years from now. I suggest buying a cheap 1980's S-10, or something else, for $1000 or less & keep the '59.
