Welcome to the forums! This is the place to find the answers you need!
On the top of the page is a blue toolbar, try the search function with different phrases such as "door damage" or "door hinge", etc. You may find posts or threads with a model such as yours.
I do know that bent doors and such are a difficult at best issue to solve.. If the door does not seal properly, you will have water leaks, which will rot your floor eventually... the hinges may or may not be available. Try InlandRV.com or VintageTrailerSupply.com for parts. You may need to repair what you have.
I would take some digital photos and post them in this thread... click the go advanced button after your key your questions, statements, and you can upload your photos. The pictures are really worth a thousand words here. People can respond much easier.
Good luck! And, again, welcome to the forums!
