How to accept payment for Travel Trailer

I like transferring (wiring) funds, financial institution to my financial institution, even if it's just across town...I pay the transfer fees. If it's cash, I'll meet em at my bank. Once that's complete, next stop is the DMV office where I sign the title over after the buyer pays the sales tax, registers the unit (if it's Texas) and both parties sign a statement of the unit's condition. Then the buyer gets a Bill of Sale. If the buyer's demands get too crazy, I'll back out of the deal. Very few transactions test my limits except property and it must be done in a public place, My way or No way.
I'm up front with this process if the buyer sounds interested, but before he commits.
