[Chester Stone]

Perhaps this observation will help explain why. When in travel mode, the front of the coach utilizes one height adjustment valve thus keeping the frame from flexing or twisting. When in level mode, the front of the coach utilizes two height adjustment valves thus allowing the air bags to level the coach from four corners. In the level mode there may be slight twisting and the slides should not be moved until the frame is not flexed. Otherwise, the slides may be damaged.
