2000 Concourse Club repairs

Sunny day today so took off the fridge vent and it seems to be pretty dry in there. Time to look for any other area where the step leak can be happening from.

Looks like someone has already been in there to caulk seams, but I think I’ll reinforce them later anyway.

Yep, that looks pretty dry. Good deal! Also looks (I think) like you have the same build I do. That is, there is a 1/2' plywood "floor" for the fridge compartment. If you could see that you'd see it does not quite "seal" against the outer wall (which stands to reason). Then they took some of that 1/8" vinyl-coated wall material (like is in the kitchen) and laid that on top of the plywood such that it went right out to the wall, and then caulked that in place. As a matter of fact, that's how the whole compartment is done (which is required to be separated from the living space air, as you have combustion byproducts in there). The walls are "close" and then pieces of the paneling are put in and caulked to seal it more precisely.

At first I thought 1/2" floorboard to support the fridge seemed a bit meager, but when I really thought about it (when taking it all apart and removing the fridge), the legs/weight are mostly on the outside edges, so the plywood is there more to make the sealed compartment.

So.... hmm. Let me ask you this: What is the forwardmost point that has water damage? Because sure, something right at the back might be leaking (and that is even probably most likely), but given that the floor is flat and water runs downhill, it's possible it came from further forward. But then I'd expect to see damage ther too. Oh, and while we're at it, what's the "highest" point of water damage (like that closet latch area - that's an interesting one).

I wonder if it's a marker light, the door frame (look up on top where it joins the roof area - that caulk can dry out), a ladder leg (on the roof say), or a rail leg. Or it could be more than one thing. But we know the water didn't leak "upwards" anyway. So a taillight leak couldn't rot the closet door latch, for example.

I would really like to know which way the PO's driveway slanted!

I definitely am parking with the rear end downhill for now!
I checked the generator area today and it too seems to be pretty dry.

I inspected the rear door again and I notice that the seal is pretty much flattened and perhaps doesn’t make a good right contact with the jam. I believe the leak is coming from the door seal. Why else would the lower floor well be wet and nothing else above it. The MDF soaked it up like a sponge and I think that’s why it swelled up higher and looks the way it does.
By the way, the closet door latch wood is not wet. It looks like it was broken by someone trying to open the door without pushing the latch button. If someone doesn’t know about the push button, I’m not surprised if they try to force it. Anyway, it’s not wet up there, just broken.
I’ll be indoective other areas of possible water intrusion as the days go by. I’m actually driving the rig to work every day, and I have to say, it’s great having a nap midday!

Great to hear a report.

The closet door latch being broken solves a mental mystery for me. I could NOT figure out how that could have gotten wet!

Perhaps someone bungled the latch, but another possibility is that it is fairly easy for the MDF to just do a "cardboard peel" type of thing and release itself from itself, if that makes sense the way I described it. Mine had that on a lower door (I think it was the one under the stove) where the hinges let go not due to water but just because the MDF peeled apart from itself (helped along by screws going in for the hinges).

On the door: Mine has pretty much no weatherstripping now, and even in heavy monsoon rains/wind didn't leak at all. Not saying yours didn't, but... If you go up on the ladder and look at the top/outside of the door, you'll see there is a cauik bead on that little "hood" in the fiberglass where the white painted door frame joins the fiberglass body. Could that be it? That faces "up" and is exposed to weather.

Also, have you looked under the false floor in the closet? (Sorry if I forgot and you did already.) That will allow you to see the plywood floor between the generator and the rear wall. To explain: That carpeted sort of half moon bit of the closet floor that is aft of the generator box is a false floor. There is a loop that allows you to pull it up and it just completely removes (you can put it back). If the loop is missing or tucked under, just know you can completely lift it up (just pull up on the shag ). The reason it is there is that the AC junction box for the generator wiring is under there on the plywood floor. So that little carpeted panel sits on little wooden cleats that are attached to it. If it's like mine it will just pull out. You might get some good clues there.

Another thing to know as you noodle: If you were to pull the carpet up in the back hallway, you'd see that the lower inside rear step is part of a fiberglass "pan" that sits on top of the plywood floor (at least in mine). So.... not sure water could run across the floor and onto the step? Maybe if it traveled over the carpet pad or something.

The mystery continues... (for now - I know you'll suss it eventually!).
