NADA retail base value is $5,550. Not sure what options you have, but it sounds like you would have to put almost as much into it as it is worth and there are plenty of Palomino truck campers on Craigslist. Use Search Tempest and you can search the entire US Craigslist. You might be able to come close to matching what you have for what it will cost to fix what you have.
I would move on, but that’s me.
