MM 2106 & 2108 - shower plumbing access

[backtrack15]

I'm curious if anyone has come up with a simple/clever way to check under the shower pan for leaks in either the shower drain line itself or the pressurized plumbing hidden in that area (e.g., city water connection, shower hot/cold water, outside shower supply piping)?

It seems pretty inaccessible, which isn't great as I'd like to occasionally inspect it to make sure all is well. The best I can figure is to use a camera to poke around in there, possibly via the shore-power connection.

From memory, isn't there a passageway behind the toilet for plumbing lines? Couldn't the top or front of that be removed?

There is a plumbing passageway, so it does seem like a good access point for a camera (much better than the way I mentioned). I had forgotten about that. There might be a way to see in from the pantry as well since the shower drain heads that way. It's too bad they didn't put an access panel on the side of the shower pan toward the toilet.

There is (on our 2108 anyways) a lid with two screws right below that shower area at the bottom of the trailer (left hand rear corner) From the factory they don't cut that weather seal so the "flap" is just screwed on and when you loosen it you just see black liner. I'm thinking the drain is accessible above that liner/flap so if you were to cut the liner you see the drain. that's why that flap is there so you can close it again. it's pretty low tech.

I have not cut the liner (yet) as did not need to on ours.

Thank you! I’ll look for that.

Not model specific but on average the shower flooring is built up from the finished floor. Engineers use this not only for the drain plumbing but also for furnace ductwork. In my bath, the furnace supply duct comes in under the shower. I can remove the difuser and get a pretty decent peak.
Then I found in my coach, the interior wall that separates the bath to the living area has a furnace return air grill. Again, this location is under the shower pan. No duct work, just an open plenum with a vent grill. I remove that grill and can see the full underside of the shower floor. This plenum aides getting air back to the furnace. Look for rectangle shaped grill just above floor level. You may luck out like we did.
