2005 Endura Super C 6340 cab over water leak.

Does anyone have an Endura super c with a water leak over the the cab? Been searching for a while for a leak that totally rotted the wood platform over the cab. Suspected the side window leaking but that was not it. What have you experenced on yours?

I have a diff model, bought a 99 Conquest Class C last year but from what i read regardless of leak location over cab/ or brand/ year, water settles to lowest spot over cab and sits/ soaks/ rots undetected... Moisture alarm up there from factory in all brands now seems like it would be a GREAT idea?... and a DRAIN? and provisions to air dry? Check caulks every 3-months?

THE UPPER ROOF PANEL OVER-CAB rolls down to a 4-5-O'clock position, where it anchors/ seams w/ the lower panel visible thru windshield. (On mine), this joint is bowed, appears to have rotted out the anchor wood, and will push water in as you drive; MAKE SURE THIS JOINT IS WELL CAULKED/ SEALED, (I recommend) masking tape to control caulk, makes much neater joints, once dirty, than smears that were OK when clean/ new. LUCK

I have a 2005 Gulf Stream EnduraMax Toyhauler Super C (35') and did experience water leaking below the cab-over bed. It would only leak when driving in heavy rain. The water came in the area just behind and above my head as I sat in the drivers seat.
I sealed the area outside between the Chev C5500 Kodiak cab roof and the fiberglass Bed bottom. There is a rubber seal there but it started leaking around 35,000 miles. I used a clear sealant and haven't had trouble in the past 14,000 miles.
