I am in a manufactured house and the back door is not solid door. I want to get a better door but right now i can't.There is nothing i can do is there to make it stronger is there? I want to get longer screws for the hinges but they are gold so can i get longer screws in gold? What about those braces (don't know the name) that sticks out around the door knobs that help keep them from being pried? It has a dead bolt on both front and back doors and a slide lock on back door. What else can i do? thanks
