Had the same problem, with the stabilizers having a life of their own (scares you to death in the middle of the night, that's for sure) and actually took it back to dealer to have them checked out and could find nothing wrong. When we check after their spontaneous raising (never lowers) we always find it in the on position, even though we know we shut it off. Don't laugh, but my guess is that someone nearby has triggered it with a remote control device on the same frequency. Last week at an RV park in Beaumont, TX, we found it happened at about 4 AM, the same time a neighbor got up to leave for his job at 5. We noticed it happened again at about 4 PM when he returned. Anyway, that's my theory, since it doesn't happen every day at every park we go to.
