We have a 2013 sabre 33 rets and having issues with paper wrapped wood used for cabinet frames. It appears the glue is not sufficient as we have buckeling on almost 30%- 40% of frames. Have seen them in Kitchen, Living room and bath room, there high and low. they are getting progressively worse. Has anybody else had this issue and what is the solution? Love the fifth wheel , but this is unacceplable.
