I have a 2017 Pinnacle three slide. I have come cracking of the skin at the lower front corner of the bedroom slide. I have been talking and looking at other Pinnacles and have found many that have this issue. I have been contacting Jayco with this issue and they say it is not their problem. If you have this type of issue ease contact Jayco customer support. If we keep letting Jayco know of this we may get some response from them.
