Welcome to the forum and to the scrap business. I am happy you are charged up for this project. The amount you will learn from it will be an education you can not buy.

There are several threads on others who have documented scrapping trailer homes. I don't have any personal experience but have gleaned the following: There is a lot of trash material that has to be discarded. Most have concluded that the next trailer house they take on the home owner will have to pay them, free will not be good enough.
