Amerilite 24RS

I bought a seldom used, interior stored 2006 24RS Gulf Stream Amerilite trailer from the original owner. I have found that the camper box was not set properly on the frame at the factory. There is less than an 1/8 inch tire clearance on one side and over a 1/2" on the other. This has caused the inside of the tires to rub on the "box" (above the frame) on one side during turns or swerves. The inside sidewalls of these original tires are literally melted off to the cords.
Has anyone here heard of this issue with Gulf Stream units?
