Excellent advice given so far that I entirely agree with. Check with your state's DMV; the rules vary a good bit between states, I think more so with trailers than with motor vehicles (but both do vary).
Here in New England, most (maybe all) of the states won't issue titles for vehicles over about 15 years old, or at least won't issue them as a matter of course. Needless to say, they also don't require them when registering a new-to-you vehicle of that age. Of course, South Carolina is not in New England by a good many miles.
