This is a very nice looking Stahl Challenger X with a high roof mounted on a conventional cab single rear wheel chassis. This particular photo was found on the site of Lancaster Truck Bodies, of Kennett Square, PA. I've seen many Challenger X units, but have never seen this with the high roof. Very nice.
The ChallengerX Service Body is an economical, rugged and dependable, utility service body that is the perfect solution for tool storage needs. Concealed door hinges with spring loaded door holders hold doors open at 90° for easier access. Automotive clip-on door seals protect your assets from the elements. The ChallengerX also takes advantage of an exclusive “Lock-Bolt” mechanical fastening system. This system reduces 80% of the welding used on conventional service bodies but is stronger and more consistent than traditional welding construction.
