It is an 11 year MH and I am sure it was sold "as is". Check your paper work, in FL they include an "As Is" signed form. However, many states, your insurance will cover the broken windshield. In FL there is not even a deductible.
The windshield frame rust is very common in older Winnebago's. Many were not discovered until the windshield starting leaking only to find the frame behind the windshield was rusted away.
