We have a 2009 Winnebago View (Sprinter-based) with the cabover bunk and an opening skylight just aft of the bunk. In the last rain, water started coming out of the skylight frame. It seemed to be running under the roof and above the ceiling from forward of that point, but I'm not sure. I suppose it might have actually run forward from the skylight frame. Nothing looks amiss on the roof. The skylight looks well sealed and so does the antenna just forward (suspiciously forward, I should say). I have some Eternabond and plan to work on it on the next sunny day, but it would be nice to have a better idea of what I'm looking for. Has anyone had a similar problem?

Had a Class C years ago that kept leaking above the front bunk and could not find it.
Finally in desperation you pulled the ceiling down and found no insulation had been put in a section of the ceiling above the bunk. Condensation was creating the leak when the heat was on inside and it was cold outside.
Probably not an issue with the unit you have.

If you already have water coming in...you really need to address this properly, I suggest. Take it to an RV repair shop that can effect a pressure seal test. That way...you find out exactly where your leak(s) are and can repair, otherwise, you are just wasting valuable time and increasing your $$ risk.

You might try this to find leak. Get a 20" box fan and place it in front of a window that is close to the size of the fan. Support fan so it will not fall. Seal around fan to edge of window with cardboard and duck tape. Turn the fan on high to that it blows into the RV. This should pressurize the RV. Go outside on the roof and use a bubble solution at any seams, joints, or roof items.

Std spots to focus on are clearance lights, seams (especially where the roof meets the cab over) and the antennae. On the antennae make sure the rubber boot which which is suppose to prevent water from running down the line is well secured -- also the std bat antennae has a super thin rubber washer as part of the crank mechanism and if you haven't replaced that since you bought the rig chances are that's long gone and another place which might contribute to leaks.
I agree with the comments concerning pressure testing - might save you some time and worth the $100 or so it costs.

Go outside on the roof and use a bubble solution at any seams, joints, or roof items. I have toyed with the idea of just taking a simple cardboard box of a size large enough to fit over the 14"x14" vent (when cranked open) on most roofs. Cut off the top and bottom of the box. Then lay a 20"x20" box fan on top facing down. The pressure inside the RV does not have to be that great since falling rain on the outside does not have that much pressure. Driving in the rain would increase the pressure, but not that much in a leak area. Might have to use "duct tape" for a better seal depending on slopes of the roof etc.

I had a very similar problem. I opened the ceiling at night, put a bright light in and looked on top for a glow. Nothing. I never did find it, but the leak stopped when I scraped off old caulking and redid it.

Actually, I might try using the Fantastic Fan on reverse. The Winnebago front cap doesn't have many places to leak - clearance lights, radio antenna and skylight. The seam between the front cap and the main roof is behind the leak, so that's not the problem.
