We have a 1997 Class C Tioga Montera that has a water leak in the over cab. This seems to be a common problem on the blogs and I am hoping to find some guidance on self diagnosing and fixing. We caulked the windows and clearance lights and have pulled the interior paneling down on both side walls and under the window and are currently cleaning out the mildew and allowing the inside to dry out. Things are coming along quite well and the MH actually already smells much better. We are planning on installing an entertainment center using the back half of the bunk and keeping the front part for a single bunk. Today it rained and we found that after all the caulking there is still a leak. The leak is right above the overcab window so we think it is probably coming from the clearance lights but who can be sure? We would like to pull the bunk ceiling down to see from the inside the extent of the damage and possibly find the leak. The bunk ceiling that is affected starts from the top of the window wall to wall to about 1/2 way to the center of the bunk. The seam stops here and then begins the rest of the inside of the MH ceiling. We cannot figure out how or if we can pop that small section of ceiling panel out from the inside. Wondering if this is something that is installed from the outside before the roof is put on. My husband wants to just tear it out since we will be covering it with an entertainment center anyway, but I would first like to see if there is anyway around that so we can salvage the panel and put it back up when the repair is complete. Any ideas on how to remove without damaging that front ceiling panel? Would greatly appreciate any advice!
I don't know whether this is similar to your situation, but there is a panel above the front window in the cabover of our Minnie that can be removed to gain access to the inside of the clearance lights. See picture below. The panel goes from above the window to the roof line and is held in place by two metal strips, top and bottom. The metal strips have grooves that the edges of the panel fit into. By pushing on the panel midway between the strips, the edges pull out of the grooves allowing the panel to be removed.
