  • because in the Tuscaloosa, Alabama plant, the bodyshell is rotated 360 degrees during painting. The roof panel is attached to the body with screws and 10-millimeter spacers, so the steel and aluminum , which expand at different rates, can cure together after painting. Once dried, the roof is affixed to the body with adhesive. Other factories that don't rotate the body use tabs on the roof panel to secure it to the body.
