Hey everyone! Complete newbie here! My wife and I actually were thrown headfirst into the rv scene when we won a 166 retro! We are crazy stoked about getting out and enjoying but I have a concern. I'm a big guy and I've noticed the toilet rocks quite a bit and it appears it's from the floor and not the actual toilet its self. So I ask has anyone done anything to beef up the floor and is it even doable? Never messed with rv stuff so don't know of its similar to a home toilet as far as fittings go. Or if I'd run into problems trying to get the toilet to reseal if I add something. Look forward to your response and thanks for letting me join! I'll try not to bug to much!

Well first off - congratulations!!!  That's a crazy-cool way to end up camping!!![thumb]

I have the same issue with my 150, and I'm also a large guy.  You're right - it's the actual shower unit/holding tank that it is mounted to, and not the toilet itself that is the problem.  Because the toilet sits on top of the tank, I don't believe there is much to be done.  I sit gently when I need to sit, and try not to rock a lot.  After one season of camping we haven't had any cracks, but I do believe others have had some problems with this...

This link might also help you understand the construction of the base...

Thank you. I kinda figured that was the case, been debating on trying to mount a sheet of aluminum to the entire floor under the toilet to sturdy it all up. But time will tell. For now I'll do my best to "sit lightly" and thank you! We are crazy excited to make some memories in it

PB said it all.  All RV's use the plastic toilets and they do rock a bit.  The key for us big guys are to stay still and not cause unneeded stress on the base. 

Welcome to the wonderful world of Retro and may God give you many fun and safe trips.

Keep us posted and pictures would be great.

So the toilet issue still worried me so I bit the bullet and tried this. It's a sheet of 1/4 birch. I "dry fitted it and snugged the toilet back down. It reduced the rocking by almost 60 % I feel better. The wood panel is now in the process of being painted with some hi gloss oil enamel then I'll read seat it and silicone the edges. It will take a few days thanks to dry time but I think all in all it will work!

Looks good!  Are you bonding it to the floor with silicone, or just sealing it in?  I'll be eager to hear the end result of this!!!

In the process of sealing it with oil based paint. My plan it to use liquid nails to bond it to the floor then seal it all in with silicone. Hopefully my paint will be dry so I can finish it up and post pics.

Nice upgrade - I'm eager to hear how it comes together...[cool]

It's all done! As stated before it substantially decreased the rocking of the floor. And it's hardly noticeable.
The board got 3 coats of oil based paint to each side and the edges. I scuffed the plastic with 100 grit sandpaper to give it a bit of a tooth for the liquid nails to grab on to.
I set the board then replaced the toilet and tightened it down to ensure the floor and my board bonded tightly. It sat for 24 hours.
Then I removed the toilet and siliconed the edges and around the flange.
I also added a extra seal to the toilet as I raised the floor a full 1/4 in. I just wanted to ensure I still had a good seal. It may not have been needed.
I consider myself fairly handy when it comes to tools so I wouldn't say this was a hard upgrade. I found it quite easy and the painting was the worse of it for me just because of the dry time between coats.
Hopefully this helps the others who feel there toilet shouldn't move as much as it does.
Happy travels!

Nice upgrade and well executed!  I think you just gave me another project for my to-do list...

Has anyone replaced the plastic toilet or the seat in other models? Our toilet makes horrific noises-squeaky and weird crackling plastic on plastic noises when someone sits on it. I am thinking in the long run of putting a ceramic toilet in or at least a wood seat to see if it makes that sound stop.

I was in the Dometic site they are the brand our retros have  and  I believe they have a ceramic model for rv's.  Not sure if it fits our little retros or not.

i really like this idea! My only concern is the "low spot" where you cut the board to go around the vent pipe. Might make a place for water to stand and works its evil on the board.
