Thor Ace Shower leak

I thought I would post my experience with my 2014 Thor Ace 30.1 shower leak.
We camped at Mama Gerties this last week and I noticed some water dripping down onto the left rear tire which is right above the shower. The unit is under the extended warranty but Camping World is a 2 hour drive. I started looking around at possible areas for a leak. Looked above the tire and I see a rubber cover screwed to the floor. I removed the cover and access to the P-trap is right there. The fitting that screws to shower drain had cracked and was leaking. The cause was at the factory the pipe wasn't supported and they forced the fitting up when screwing it on. The pressure cracked the fitting, letting it leak. I picked a new fitting set from Lowes. They had the exact replacement. Replaced it, put a support under the pipe. I replaced the rubber cover above the wheel well with a piece of clear Lexan I had some scrap from. The original piece of rubber didn't cover the whole access anyway allowing water to hit the edge of the floor system.
I hope this may help someone else that may have a leak. I originally thought it was the shower enclosure but I had caulked it really good a month ago. At least Thor thought it was a good idea to put an access there.
First picture is the old fitting that the piece on top was cracked and broke right off when I pulled on it.
Last pic is the clear cover complete so I can just look inside to check it.

Are you sure the shower floor isn't flexing and caused the break in the fitting? Perhaps a flexible section of 1.5" drain line would allow movement?

A window in a roof is often called a moon roof or sun roof. What do you call a window in the underside of the vehicle?

The floor is penty solid. The problem was the pipe running horizontally was angled down and they pushed it up to hook to the shower drain and the pressure was pulling it away from the drain. I pushed it up and put a support under it.

Not sure what to call a window under the floor?
