Aluminum service body. Roll up doors, shelving, lighting in cabinets, overhead storage, overhead ladder rack, and center area for generator/welder or other equipment, etc. It's a beautiful service body from a firetruck which would fit nicely on single axle 5 t truck, heavy trailer, or similar. Still mounted on truck. Can be viewed to discuss options for serious inquirer. Would be willing to prep to suit to some extent. Give me a call if interested or have questions. Thanks.
