If your dream is to camp in it, then it MIGHT be worth fixing it. If you have some memories attached to it, then it MIGHT be worth fixing it. If you have no feeling for it, then maybe it would be best to pass it on to someone your family who would care about it.
If you or no one in your family wants it, and it is not beat up on the outside and it will roll down the road, you might get maybe $1,000-1,500 for it. I've heard they bring $300-500 for scrap. I'll bet if you put it in the classifieds (see the tab at the top of the page) with a few photos, someone will make an offer that would be really excited to get it.
