Checking my recently purchased 1997 u320 auto leveling hwh operation and let the coach level itself. Front dropped and side to side worked fine. Blinking light on panel on auto and the rear did not come up as needed. Manually raised rear till low light went off. <br/><br/><br/>Turned everything off including house shutoff. Came back a couple of hours later. No movement. <br/><br/>Turn on...
