Purchased new motorhome online, help with title questions

Personally, I would be real careful about a transaction you describe. Your giving him a guaranteed payment, he should be giving you a title. You also have to be sure there are no leins on the title, that it's free and clear from the instituation that was originally financing it.
Once he's got your money, and you have no title or don't get one your only recourse may be the court system. In the meantime your without your money and your motorhome.
