"C" Channel and Water Leaks

I'm wondering if anyone has seen the construction details of the C-channel on 90's era rigs. My question is whether the C-channel "trough" would contain a leak that came down inside the wall and then direct it to a joint or seam in the channel, either at the door frame or where the channel must curve at the front and rear of the rig. To date, my leaks have only shown up on the inside floor at those locations.

Do the hold-down bolts have a washer or maybe even a glob of SikaFlex that would prevent water soaking into the plywood beneath them? Are the only joints in the C-channel in the aforementioned locations?

The reason I ask, is that there are considerable areas of my rig where I can not readily check for moisture at the wall/floor juncture-- along much of the street side, where a cable chase covers it, and back under the kitchen counter (beneath stove and furnace).

The concern is, a small but ongoing leak, that just wets one of these hidden areas and rots the floor where it is attached to the C-channel. Do I need to be checking every linear foot of my wall/floor juncture with my moisture meter, no matter how difficult the access?

Still wondering whether anyone knows what the c-channel on the 90's rigs looks like in order to address the above question. Thanks--

I believe the newer c-channels had drain holes on the outside edge but the gaps at the 4 corners and other places are still there and not sealed. I don't think they sealed the protrusions through the c-channel either. I sealed my c-channel and put in a bridge where the gaps where. I also caulked up any protrusions through the c-channel. I had to add drains to mine since mine is older. Remove a wall section where you have leaks and see what you find.
