I have read several posts on people worrying about Rust on the chassis underneath of Motor Homes. What is the big deal? I would expect most undersides of motor homes after a couple of years to have lots rust underneath, especially if based in northern areas where they use salt on the roads and in coastal areas. The under carrage of my motor home has lots of rust on chassis frame and some of the parts. It was based in Tacoma Wa for 8 or 9 years before I bought it. The rust on the underside of my present motor home is not flaking kind of rust, but the frame and other parts are rusty colored. I don't feel it is anything to really worry about. If it had been in a flood that would be another story. Anyone care to comment.
