Online Travel Trailer Sale (classified ads)

(UTAH) I sold a travel trailer that i had posted online in mid September to a woman who lived in Elko , Nevada.(Well she was working in Elko but was from another state.) I live in West Point, Utah. She had a friend who lived here in Utah contact me and make arraingments to come over and look at the trailer. When he came i looked it over really quick, I offered to plug in power and turn everything on but he said that would be o.k. and took my word that everything worked. I had just got back from camping the weekend before and hadnt unloaded my trailer yet so my generator was sitting inside where i pack it and the Tom guy asked if it was included with the trailer, and i said no, it stays with me i need it. Well he took some pictures with his camera phone so that he could send them to her. He asked me what was the lowest that i would drop my price from the $7500.00 that i was asking. I said if she gave me $7000.00 i would sell it to her. He said o.k. he would call and tell her and if she was interested she would contact me. Well she called me about an hour later and said that she loved the pictures and the trailer was exactly what she was looking for. She said she wanted to buy it and asked how she could make arraingments to pick up the trailer that next Friday. (it was Sunday when we had this conversation). I told her that i was going out of town that Thursday and that she would need to pick it up by then, she said she could not make it until Friday, but said she could get me the money before i went out of town. We made arraingments for her to get me a cashiers check for the $7000.00 by Wednesday. I recieved the check Tuesday morning and cashed it later on that day. (Let me say that we had a few problems getting it cashed because it was an out of state check, that was sent from her husbands in house care provider that was taking care of getting the check sent to me for her) I got the check problem taken care of and was able to cash it. I contacted her once again to let her know that i had finally gotten the check cashed and that the trailer would be waiting for her. She had made arraingments with another from of her whom she knew from this Tom guy for me to drop the trailer off at his house which was only a couple of miles from my house, and then she could pick it up from his house since she wasnt coming until Friday and i was leaving out of town Thursday morning. I contacted this guy to get his address and make plans to bring the trailer to his home. I dropped it off and then contacted this woman to let her know it was there waiting for her. It was a done deal. A week later i get a phone call from this woman asking me where the generator was that i was supposed to leave in the trailer. I told her that it was not part of the deal and she insisted it was. She went on ranting and raving about all of this stuff that we had never discussed before and i said to her that she must have been mistaking all of this with another phone call and gotten the two stories mixed up. Well she kept on insisting that i was wrong and that i had cheated her and i kept telling her sorry but that was not part of our conversation and certainly not part of the deal. Finally she said it was done and over with and told me to enjoy her money and then hung up on me. So here it is almost a month later and i get a letter in the mail from this woman telling me that i cheated her and that the multiple items in the trailer dont work (everything worked in the trailer, except i did not know if the oven worked and i told the Tom guy that) and that she is going to take me to small claims court and sue me for $1,000.00 if i dont pay her and make things right. So after a long story ( which i did not include everything she had said to make me feel bad) i need to know if i should worry about this and if she has anything to go on. I know that i did not cheat her or rip her off in anyway, but in makes me angry and at the same time feel bad that she is confused with her stories and coming after me. If i could get a response of some sort that would be great! Thanks!
