In the late 1930's White made a bunch of tour buses for the National Park Service, sort of Suburbans on steroids. They were used at Glacier and Yosemite, and maybe a few other places. Since they had crash box transmissions, the drivers were known as "gearjammers". In the 1980's Ford took on a full restoration of a bunch of "Red Jammers" for Glacier, retrofitting the bodies to F-450 frames and running gear. They spent something like $200K per bus. I rode one on a tour of the park several years ago. Now they run gasoline/Propane V8 engines and automatic transmissions, but they still call the driver/tour guide a "jammer".
