Google aerial photos of airventure.
Open the second link that gives a satellite view, open the view and zoom in on the east (right) side of the airport at the thousands of trucks being stored there.
There are some that have been there for over 2 years and are being brought back in for repainting because of rust. There are Oshkosh trucks being stored all over Winnebago county.
Easily a two year supply sitting around.
They will be half price with the defense budget cuts just to break even on storage fees.
Just saying what I see when at the airport.
