Having problem with auto leveling system. Out camping now on a fairly level spot. Was using "auto level" and suddenly the screen goes blank before it finishes leveling. Tried again with same results, blank screen before completely level. Noticed shore power was not completely plugged in and I guess battery (only have one)was not sufficiently charged to complete leveling process. Plugged in shore power, tried again with same results, blank screen before completely level green light displays. Now I have two tires off the ground, so I hook up trailer to truck, raise all legs and lower front legs, disconnect and try again with same results and after three tries again two tires are off the ground. Hook up to truck again, raise legs, turn off all power, turn off "red" battery switch, try turning on leveling system "on" button and no results as expected. Was trying to see if leveling system would reset with no power. Lowered front legs, disconnected from truck and tried to "auto level" again with same results, screen goes blank before complete leveling. Called dealer service rep and he said leveling system needs recalibrating. Anyone have this problem before? Anyone know how to recalibrate system?
