Hopefully, it should stay in place going down the road.
Photos attached.

Couple of questions about this fix. I cant tell from your pics but does only the one area need the support or is another piece needed for the other side of the p-trap/drain.

Second question. If using a 2x6 is there room to shim the 2x6 up from the bottom to push it up against the pan instead of using the 3/8 board on the top of the 2x6???

Jerry, Let me look at some of my other pics and see if I can better answer your question.
Its been a couple of months since I did this and I've not only slept, but had alcohol since then.
I do know that a 2x6 was part of the fix, and that I still have a little bit of a soft area that I feel when in the shower, but not nearly as bad as it was.
More to come.

Ok, I think I remember, now.
I used the 2x6 on the bottom against the bottom of the RV floor, supporting a piece of plywood up against the bottom of the tub floor. The white stuff is glue to try to glue the 2x6 to the plywood.
Then, once I was happy with the placement of these two pieces in the hole, I used 2 wood screws with washers to hold the 2x6 in place on the RV floor.
See if these three photos show it better for you. 1610 shows the "whole" picture, 1611 and 1612 show the ends.

I believe I wanted to provide a little wider support for the tub floor with the plywood, thinking the 2x6 was narrower than the plywood. That is the only real reason for the way I stacked it, as far as I can remember.

Get back to me if you need more clarification.

This area is pretty tight to work in and get to. Don't screw your neck up trying to get to it. I'll come down and give you a hand if you want me to.

I had a soft area in my Miramar by the shower drain too. I cobbled together a pic fix. I used two pvc toilet bowl flanges, one threaded coupling, a short piece of pvc pipe about 6 inches long.

I essentially made a jack on the kitchen table from these pieces and sanded one end so it would spin on the piece of pipe. Very hard to describe! Think about a screw jack,or jack post from a basement.

There are some step stabilizers for rv steps that could be modified to fit under the shower floor. I would have used these had I known about them before I made exactly the same thing from pvc toilet flanges.

Pretty significant soft spot,around 8” diameter in front of couch in my 2017 axis. I cannot see it from below there’s seems to be a subfloor or insulation covering that area down there under
Any suggestion?

Do you know the cause? If it hasn’t been there previously can you think of any way it could have gotten wet? If it’s always been there and isn’t getting worse you might just live with it. If it’s new, damaged and needs to be fixed you might have to pull up the floor and cut the damaged area out. Which isn’t as cataclysmic as it sounds. Look at it as an opportunity to upgrade your flooring as well as fix a problem.

I don’t think the soft spot is from water, it’s behind the drivers seat in front of the couch. All of the threads I’ve read are around the shower. I cannot see it from underneath it looks like there is a subfloor some kind of insulation that looks like it can’t be removed. My thought are that it’s cosmetic and perhaps they left out a support where there should be one. I’m trying to upgrade and 2 people that looked at it would not be convinced it is cosmetic. It’s right in front of the couch so I’m thinking I could take the couch out(where I found the drain for the water tank) and see if I might be able to peel back the linoleum enough to take a look. With what I know I’m convinced it’s not a water problem
Thanks for all the input it is much appreciated

I think the soft floor problem is in all RV showers. I also have it and my solution is to install a wooden or fiberglass platform that sits on the bottom of the shower and remove it when finished to let dry. You can buy already made teak ones but are very expensive or just make your own with pine or cedar slats screwed and glued together and sealed with varnish or uerathane. The platform spreads your weight over a larger area. I have not started the project yet but will post pics when I am done. ( I wanted to use old hockey sticks cut to size but got the `Not in my shower refusal`)

If it wasn’t always that way it does seem like it’s worth investigating. Hopefully you can access it without destroying the flooring. Usually though soft floors come from ongoing water intrusion and I hope that is not your case. Water is funny stuff and if you’ve got some it could be coming in around a slide, a side window or even from the roof. Good luck.
