Not sure if you've got the manual for the system, but just in case here it is. If you haven't been shown how to recalibrate the system to what YOU say is level, it's on page 3 under "Zero Setting The Control". Very simple. We leveled ours using multiple levels in key places inside, then set some bubbles front and side and set the system. We did use the auto feature for a while, but after having to recalibrate, or zero the system several times, we just went to using it in manual mode all the time.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
