We have the 2019 Pinnicle 36SSWS and so far no Crack in side wall. We used our pinnicle 5 or 6 times on 400 to 600 mile round trips and once on a longer trip of 1068 miles round trip. The only problem we had was a water line was kinked and the sail switch in the furnace went out. We could not winterize the trailor due to this and could not keep it heated Until our dealer could get it in. So Jayco approved a mobile teck to come to my house and fix both. (not 2 seperate trips for RV teck Just one visit) I paid the guy and Jayco sent me a check in about 3 weeks.
