Is there something special about the Tacoma that would appeal to a collector or enthusiast? Those types of buyers are usually very good to deal with, and I wouldn't worry too much about getting shafted.
If the buyer is just looking to get a good deal on a run-of-the-mill vehicle or is a young kid making an impulse buy, he will probably never come up with the money, and I would not deal with him.
I have also found that a lot of out-of-state buyers will eventually say the shipping is too much and want you to pick up the shipping. It is their plan all along.
Why not drop the price by $1K and sell it locally; or, ask for full payment via PayPal (just don't let him use a card and charge you the 3% fee); otherwise, BCGPER gives the best advice IMHO.
