Adventurer Camper 2012 Black Mold -need advice ??

The OP stated that the seller told her that it had only been used a couple of times. So the antenna was probably knocked off by the previous owner and since it is used it well most likely be sold "as is". If the dealer wanted to be an a$$ then they could just tell you it was sold as is and it is up to you if you want to have it repaired. If they help you out then good for them, I hope they do.

Good Luck
