  • Page 6 METHOD OF USE The levelling system for camper vans, motor-homes, trailers etc. provides stability and levelling of the vehicle on four hydraulic feet, exploiting the run provided by suspensions and shock absorbers. Once levelled on its four feet, the vehicle becomes much more stable and no longer experiences annoying rocking caused by walking. On 4 feet, 95% of vehicle weight is removed from the suspensions and leaf springs, providing these parts with a longer lifespan.
