Abstract: A levelling system for a travel trailer wherein first the tilt status of the trailer is sensed, and then, by means of controlled jacks on each side of the trailer, the trailer is first levelled about the pitch axis, then levelled about the roll axis, and then stabilized by bringing any jack not in contact with the ground into contact with the ground with a selected pressure.
