I appreciate your detailed reply and I totally understand what you mean as far as low miles goes. This one has been used locally maybe once or twice a year according to the owner, old lady that her husband passed away last year and she will not use it anymore.
They took good care of it and maintained it well. New front and tag axle tires, new airbags in front, new microwave, refrigerator and tv. She said there are no known issues at all except for the brakes might need some work in the future, I think original 30 years old brakes as well.
According to the Winnebago brochure for that model, it's the Chevy chassis with the 454 engine (I believe it's the carbruted version).
I was really amazed at how someone could keep a motorhome in such condition for that long, asked for more close up pictures of exterior to look for flaws but honestly can't find any in or out.
As much as I like to buy it just for it's unique character, style and mint condition, but taking your advice into consideration, I don't wanna end up with a money pit either. Also, if you buying this one, how much would you pay for it?
