I would like to suggest a category for threads for selling Rv related items by members. For example, I have a winegard antenna that I no longer use. Could we allow members to post items like this for sale?
You'll have a much larger audience if you post sale items on the sites and forums that are designed to add some protection for you and those that are buying.
Think about it ... somewhere along the process you will have to reveal personal details about yourself to the buyer. There is no control on this forum in that regard.
How will you collect your money? Will you ship the item to the buyer and wait for it? Will the buyer send you the money and wait for you to ship the item? Good luck on that!
There are many places to sell products that have protections built in to keep the fraud to a minimum. This isn't one of them.
