We used to have an ACE. The magnets would never hold the bed frame to the ceiling. We ended up buying a set of slide locks and pinned the bed to the ceiling using the rail the bed rests on. Worked great, easy to install and remove and the bed never moved. That said, yours already got racked out of alignment. Either the actuators themselves are out of sync or the bed frame is bent. I would resort to taking it to a dealer. Our ACE had this issue when we bought it. I actually think someone hung on it bending it at the dealership. Thor replaced it for free. But that was new.
