Just my $.02 worth but I would take a shot at selling. Definitely post an ad in the
Trucks For Sale forum. You can post all the details and as many pictures as you like to help folks get to know what you have and perhaps make a deal.
As Waveski said, Facebook Marketplace is also a good popular venue that could find a buyer.
If you don’t sell it intact, you can always switch gears and offer to part it out later.
