Ivan, the coach on auto Level will level ok then sleep after 30 minutes. We could hear it adjusting, then again 30 minutes later adjusting. After 5 to 8 hours the coach would be leaning to the left, always drivers side. Today, it levels ok but starts adjusting in 5 minutes, and within 15 minutes it is leaning to the left, but down really low in the left rear and up high at the right front. Erratic adjustments and eventually shutting itself off. All this is happening on a mostly level concrete slab.
