Class c Itasca water above cab - source?

[Cubs2015]

Hello folks. Bought first used RV in fall. 2006 Itasca Spirit, a class c with the bunk above the cab. This spring noticed bunks soaked, lots of water at front of bunk. In looking for the source, one possibility seems to be the drivers side fiberglass wasn't sealed in cab area. Dried out best we could. Have been putting paper towels under carpet that lines inside roof area, still coming up wet after a few weeks.

A couple of questions. Anyone had similar problems that they can share? What is the foam piece under the carpet on the ceiling area for? It has troughs that run side to side and that seems to be where the water is still collecting. How to get carpet on ceiling of bunk removed so we can see the damage better?

Thanks in advance for any help.

Hello my first mh was a c does yours have marker lights on the roof mine did and they were leaking the gaskets had failed from sun and the weather. Also look very close at the seam where roof meets wall some are calked some are overlapped that is a good possibility for a leak when it was parked for the winter was it 1 outside if so was it level i learned to park mine on a slant ether front to back or opposite and if possible a tip to one side to help reduce the amount of water to stand on the roof. Good luck i ended up removing the celing back past the leak replaceing most of the wood. Mike

Look at the seam where the fiberglass panel with the marker lights meet the roof. That seam may be leaking. Do you have a vent up there, again check the cauck. Don't buy just any chauk, buy some that is made for rvs. Good luck!

There are a lot of discussion on here about repairing cab over bunk leaks.
One product that is often recommended and used is ethabond (sp) tape

Eterna Bond Tape is what you want. I did every seam on my 87 and fixed all the leaks. Pricey, but it works

That foam is the structure for the front wall of your cabover, where the radius is, both top (where the lights are) and the bottom where the larger radius is. Those troughs, or grooves are there so it can make those curves.
