I have the same problem in one spot in the hallway underneath the vinyl. I am planning to inject high expansion foam into the spot and place heavy weight on it to keep it from bowing up. I hope it works.

I had the same issue in my 5th wheel with the same type of floor.
You need to reinforce it from the bottom.
In my case, I had to remove the under skinning and then remove a holding tank.
At that point I had direct access under the soft area.
I then added metal from side I-beam to side I-beam and spaced it about 10" on center.
Like new again and very supported for future use.

It will only get worse if you don't support the floor from the bottom.

I also reinforced all other high traffic areas while I had it apart.

It's a very easy job but takes some time, about one day in my case.

Don't be afraid to contact Forest River. Ours is 3 years out of warranty. It goes back to the factory next month for a brand new floor - no charge.

Update: Ours goes in for a complete floor replacement the week of 8/29/16. They're also going to take care of a few other little nagging issues. And replace our awning which my DH dented when he met a tree he didn't like! (We have to pay for the new awning, which is dirt cheap compared to buying it retail; they'll install it for free.) I can't say enough about the great customer service I've received from Forest River. I knew we made the right decision 5 years ago to go with Rockwood!

Hello Chuck,*

That would make sense but what about where there is no tank? *I personally got under our trailer and removed the floor shield from the underside and had my wife walk over it . My wife is not a heavy person at all. I could see it move down about a good two inches and I don't think thats right.*

Rich,

We have heard of instances where people have described a soft floor and what we have found is that itís typically an area in the unit directly above the Holding Tanks. Those areas of the floor have fewer supporting cross-members so that tanks can be placed there. It is not a defect and since there has been no water, or structural damage the floor should be fine.
