i have a 2019 flagstaff. the recall covers what they call a nautlius p-1 water distribution system.if you have this system get on line and check out the webpage for nautlius p1 and follow all their instructions before going to a dealer. the recall states "some rvs and 5th wheels". like you i have camped in mime without any issues.apparently the factory connected some of the water lines incorrectly.
