Shower Base

Has anyone had any issues with their shower base breaking? We have a 2010 Montanna Mountaineer 326RLT. We noticed occasional water on the floor outside the shower near the base the first year we bought it new. Never could pinpoint where it was comming from. it has a garden tub with sides about a foot high and the glass door and enclosure on top of that. We thought maybe the water was comming from the seal between the glass and the top of the tub or where the glass meets the wall. We added a little extra caulking. Wasn't much water just a little now and then. Kinda dried up for a few years. Then in 2017 we noticed it again. Found water starting to run down the drain in the garage. Checked the base closer and found about a 10" horizontal separation on the wall side of the tub about an inch above the bottom. Repaired it with rubber roof tape and it has held all of last year and 3 mos this year.

I've purchased a new tub and am getting ready to install it. The old tub and the new tub both have 3/4" styrofoam glued to the bottom. I notice when I stand in the old tub that there is a lot of flexing of the tub when my weight compresses the styrofoam. I can actually feel depressions where I normally stand like the styrofoam is permenently compressed. So I purchased a 3/4" rubber mat from Tractor Supply and am going to cut a piece to the same demensions as the styrofoam. Then I want to remove the styrofoam from the new tub and replace it with the rubber one. Does anyone know of any reason not to do this? I realize it's a little heavier, but that's OK. What type of glue or adhesive should I use to attach the rubber to the new tub? Will PL400 construction glue work? Or should I just use silicone, or something else?

I also purchased a new suround (plastic) for the 2 walls. I was told by the dealer to drill out the plastic push pins or bolts holding it to the wall. Does anyone know what size drill to use? The new suround didn't come with replacement push pins or bolts. Where do you get these?

I posted the following on the "High Quality Work" thread yesterday.

Keystone QC (or the lack of it) has been a problem with my previous 2010 Mountaineer. I had the same issues with unfinished work on the structures holding drawers or using undersized screws to mount the slides for the drawers.
The plumbing off the bathroom was a disaster with the trap off of the shower drain mounted 180 degrees upside-down resulting in the drain being forced up against the flooring above, the added stress caused the fittings to come loose ultimately filling the storage compartment with water after taking a shower. Then the Fiberglas floor around the shower drain cracked around the basin set and leaked all over the place - again filling the storage compartment with water. I temporarily fixed that problem using good old duct tape and when we got home I had a fiberglass repair specialist redo the area around the drain. Then I bought and installed a decent basin set (the drain and down pipe - with better rubber gaskets above and below the shower floor) - the original had 1 very thin rubber gasket between the basin set flange and the floor. After figuring out that the shower floor had been flexing whenever I took a shower (yes I weigh 250 but I don't think I'm unique in that fact) and because the drain piping was being held rigidly the crack around the drain occurred. When I saw the space between the shower floor and the bathroom sub-floor I stopped the shower floor from flexing by injecting urethane foam between the shower floor and the sub-floor.
That fix worked very well from that point on. All of my issues occurred within the first 18 months that we owned the rig and of course despite of the flaws in the workmanship and the design the repairs were to my account. Keystone was deaf to my communications.

As I mentioned in the other thread, the Keystone Youtube blurb about quality control is nice and I think that the players mean well in their statements; it's just that they don't ring true - particularly those by the CEO at the start of the video. If he had read the comments in the forum he would know that what he was advocating was just not true in reality.
Potential new purchasers should probably watch the company videos with a a leery eye and take the comments with a grain of salt.

Had the floor of our shower crack on our 2010 in 2015. Used a patch kit I got at a box store to seal the crack and sort of match. When we got to the fall rally in Goshen that year the 15 min tech visit resulted in them taking it in at the service center and replacing the pan.
