Bought 5th wheel from private seller with lien - problems

Well, first of all, how do you actually know the post office lost a certified piece of mail?

Secondly, say he registers it, and there is insurance on it for 90 days while you guys are traveling around. During that time he gets hit by a truck and dies. Now what? It was still his property when he died, not yours.

Even if this seller was in my immediate family I would be cancelling this deal and continuing my search for another unit.
