Help-Unusual amount of rust on chassis-looking to buy

I just wrote on your other posting a dealer that might look at it, but you state here it is at a dealer and there is a lot of rust. Your from Vermont, and I am from upstate New York. My current coach has not seen winter, or salt spray which is common here. But if there is a great deal of rust I too would recommend you stay away from it. Also, there is one dealer in the Albany (Capital District) area that you should also stay away from for various reasons.
