I know this will get a bunch of the typical, unimaginative "nothing because it's a Ford" posts I'll have to weed through but just curious what you guys think I should value my truck at?

I've checked three different auto value sites, entered all the info I can and I'm getting anywhere from $13-17k. But obviously none of these let me add in the mods/upgrades I've done to it so it's hard for me to decide what I'd be comfortable taking for it. I dont need the money, I'm content on keeping it but it's kind of a waste just sitting in my garage.
