This is not a high performance racing Freightliner. In fact this straight truck with three axle trailer is a travelling Monroe shock absorber show room and training centre. Barely visible on the driver's side is a pull out body section. The truck must be kept level for this to work properly, so the landing gear (also just visible beneath) is deployed as part of the set up. There are also awnings which can be rolled out on the offside to provide some shade when space permits.
