skylight condensation

If everything is sealed properly and you have no leaks then there should be no moisture between the skylight bubble and the interior skylight bezel.

I found water was dripping from my bezel flange and that there was moisture between the bezel and the bubble. When I removed the bezel I found the skylight wood framing had damp spots and water had been weeping under the ceiling panels. Upon further examination I wound up putting my thumb through a water damaged spot in the ceiling paneling. The ceiling insulation was wet and trusses had damp and water stained wood. The skylight bubble was cracking around the inside perimeter of the flange and water was leaking through the cracks, running down and wicking onto the top side of the ceiling paneling and spreading out wetting the insulation and rafters. The skylight bubbles eventually suffer the toll of UV damage just like the plastic vent fan hatches and need to be replaced eventually. If your skylight is not cracking and leaking through your caulking on and around the flange may need to be replaced.

Its a brand new camper. There is no damage to the skylight. And no caulking is leaking. The underside of bubble is condensating and running down to the edges..

Amazing that no one had/has this issue.. Maybe no one winter camps.
