As other's have said, if you ever sell the truck, you'll probably get more for it and have an easier time selling it if it's got a tailgate. On the other hand, if you're going full time and have no place to store it yourself and no friends or family you could impose on - and let's face it, sometimes it can be an imposition - then I would definitely try to sell it on craigs list now, while there's still some time.
