I am guessing you had seen Baum Outdoors video? Im upfront with any questions. I have had 3 people reach out that had the same issue (Think I am at 63 sets sold total), I originally had the magnets inset a bit to not make any contact with the handle itself, but after the first one was brought to my attention, I made some changes and the magnets are flush and should stick directly to the handles now. I have sent replacements to everyone who had issues, and have not heard back from any that the issue occurred again. Tested them for a month before offering them, and still have the original set on my truck (4 months, 10k miles) and have had no issues. I believe its just some trucks aerodynamics make the wind come around and hit the handles at a certain angle. 2 have had issues on a tacoma, and one on an f250 I believe.
Sorry I dont get online much, so just saw the question! Hope everyone is stoked on having or getting their camper, has made trail sleeping much more enjoyable for us!
