I don't know for sure, but I'm sure the original list price of that truck wasn't a whole lot higher than 20k. You can do what you want, and the value will depend on the market you are in, but I would maybe pay half that. That is just me though. I would prefer to find one that was in good enough condition for me, and then put the money I want into it and make it how I want.
I would also like to add that whatever that dealer is smoking, find out.
