If I may, I don’t think you need them. I used them for a good year, and never did a person try to steal the tent…and as I considered it, it is about the most awkward item for a thief to try and steal, and then try to sell…and well, if someone has a car, and likes camping, they likely can afford to buy a tent.
Anyway, I don’t have any to sell, but I don’t think you’ll need them.
