BigFoot Tech Support
Last two trips the auto level didn't work because the senors seem to think the Monty was way out of level. The first time I went into calibration modes leveled the Monty, and set it. When we arrived here two weeks later, the same thing happened. I call BigFoot Tech Support, and they are sending me a new senor unit for free (I just pay shipping). I am very happy, since I have been out of warranty for over a year.
FYI, the Level Up System uses the same company for senors and control box.
