Brake Hoses, Lines/piping, And Fittings problems of the 2005 Ford Ranger

I have a 2005 Ford Ranger extended cab. I was driving it and I noticed that my brakes felt really funny so I brought it to my mechanic and he told me that the brake lines were rotted out, but more importantly that the frame was rotted out. The body mounts are rotted out, the shackles are about to fall off. He also said that the frame rails in between the leaf springs are about to break in half, and if this happened to me while I was driving I could have killed someone or myself. I am very concerned about my safety and the safety of everybody else driving a Ford Ranger that is not aware if its issue. I am also now stuck with a truck that needs work done that will cost twice as much as it is worth.
