I too have (or at least had) a Lippert motor for my rear stabilizers on my 2012 Montana. Somewhere between Charleston, SC and Sevierville, TN it fell off. Metal fatigue is all I can figure out because even though there are some rough sections of Interstate highway between the two places, it should have been secure enough to weather them. Did not have any road hazards that were run over, so it's kind of a mystery. I fortunately purchased an extended service warranty that I hope will pay for the replacement of it as they are indeed expensive. To the tune of $300 plus. Taking it to the dealer tomorrow for replacement...hopefully. Stay tuned.
