My 2014 17.56-1 has water damage to the ceiling from a leaking roof vent on delivery.
Page Bros fixed the leak, but it later showed signs of bubbling along the edge of two of the panels
Page Bros booked it in directly to Jayco to have repaired or replaced.
It must be a large job if Page Bros don't want to touch it.
Have to wait until March to get a booking, see how it goes.
