Smart and dumb ways to handle $ when selling my rv

Have your buyer do a wire transfer from his bank to yours. I set this up before I went to pickup MH, then called my bank to do the transfer after I decieded to purchase. Sellers Bank received transfer and instructions to call seller that funds were deposited in his acct. Whole transaction took maybe 20 minutes and is very secure. I carried no funds on my person and neither did seller. Dave
