Introduction

This proposal of Traymark Industrial Caravans Pty Ltd is to build a Traymark Mobile works van that is of robust construction suited to adverse road conditions. The room unit is designed to last through the rigors of constant movement throughout the state, at the same time not building in excess weight that would impede easy relocation. The materials and workmanship will be to the highest standard and meet all requirements as stated in the Australian Standards.
