The body is constructed of GRP-faced ply-board, polished to both sides to give a robust, easy-to-clean finish. All of the floor areas are covered with hard wearing fibreglass gel coat to maximise durability. The corners, doors and frames are supported by aluminium angles and where required the doors are self-closing and fitted with airtight strips. The chassis incorporates a single-axle, rated up to 1,500kg and uses a braked spring-damped tow hitch. For added stability the A-frame is welded to the chassis and the unit incorporates four corner-steadies.

Each unit fully conforms to HSG 247, VOSA and other required legislation and is built and maintained by engineers who are qualified to install and inspect LPG and electrical systems. A key focus of the design philosophy is to incorporate features to make their use as maintenance and trouble-free as possible – and therefore cost effective.
