21 Ft pull behind travel trailer

Hello my brother has a pull behind travel trailer he is looking to get rid of. The propane burners work on it as well as the oven. I am not too sure about the rest. It does have some damage to it and will need to be repaired, but wouldn’t be a bad little project. He is asking only 500$ for it, he doesn’t have any papers. If interested shoot an offer. I will try to get pictures for it soon. I know it will need to be towed as it does have a flat tire. Thank you
