I own a 2007 22' Towlite. One of the spring-loaded hinges on an upper kitchen cabinet has been broken. It's one of the two hinges that keeps the cabinet door from swinging open when you are in transit. Just for added clarification, it's one of two hinges that are at the bottom of the cabinet. Does anyone happen to know where I can purchase a replacement hinge? Any help or suggestions would be greatly appreciated. Thank you.
