Twice we've heard the Bigfoot alarm sound off while moving down the highway indicating one of the levelers was not all the way up. Scared the bejesus out of us. But when we stopped, all the feet were completely up. I temporarily silenced the alarm by lifting up on the limit switch pins, finding the one with the problem and inserting a popsicle stick between the pin and the footpad.
Called Bigfoot support, who are very nice folks by the way. They suggested a simple fix. Get four rubber vacuum line caps from an auto parts store and slip one over each of the limit switch pins. I did and we've had no further false alarms. To make the rubber cap easier to slide onto the pin, lube the pin first by rubbing a bar of soap on it. (That part was my contribution.
