Have not seen any other posts like this for these stabilizers, PSX2 with the dual motors. Only complete motor failure and the end caps tearing. May want to give them a good look over for anything that may be loose.
Just wonder if putting a tall support under the rear stabs would help? I use them with a flat pad on top(most of the time). I also extend them until the they touch and then maybe a half second more. Every once in a while I will get a one time "creak" as the camper settles but that is it.
Very rarely do I need the supports under the front but just depends on site slope. Almost always under the rear.
