I agree with you on the CraigsList thing. However, Nextdoor typically only allows people in your neighborhood and people can only join if invited. Thus, I would consider that to be a much safer alternative for both you and the buyer. Remember than with such a sale, a legitimate purchaser might be just as concerned about your scamming them by misrepresenting the condition of the grill as you are about being scammed by them in defaulting on payment.
In any even, be prepared to provide a bill of sale that both of you sign that contains all of the stipulations of the sale. For example, if the controller fails two months after the purchase, are you willing to refund part of the price. If you sell "where is, as is" with no warranty, the price will need to reflect this. Remember that the Traeger warranty only applies to the original owner and is not transferrable to the new owner.
