Rain Water Leak Columbus 320RS
Our 2016 Columbus 320RS has leaked since we have owned it. Brought back to Camping World for the leak but since it was not raining they did not find a leak??? My fault for letting that go. In any event, the water leaks in through one of the AC return vents and a puck light in the same area. I assume the rain water is coming in through a faulty installation of the Dometic Brisk Air II 15,000 unit, which is very close to the leak points. There is no evidence of any other leak in the ceiling (except occasional drip from TV antenna crank). The antenna crank is at the other end of the RV, and on the other side. I do not expect that to be the issue as the water would have to pass five lights and three AC vents (holes in the ceiling) to get to the back. And then move to the other side of the RV. This leaking has happened 15 to 20 times, both at home and on the road.
No leaks on sunny, hot days when AC running, for days. So definitely a rain issue. Any ideas?
