This bolt is subject to failure and there is a recall on it, if your coach is on
this list from Newmar you are affected. The recall adds an extra plate that keeps the shoulder bolt from failing again. Newmar performed the recall work for me at the 2016 FMCA Convention in West Springfield MA, I just called them ahead of time and they set it up. IIRC they replaced the broken bolt for free, the first time it broke it cost me $11 plus shipping from
LCI.
