I’ve got a 5 year old TT with that foam floor, and it has developed soft spots in the floor. It isn’t water related, it is just a crappy design.

Has anyone successfully repaired this??

Award tts used the same construction method, foam between thin plywood for the floors. It bankrupted them.
Our '87 30' award columbia developed soft spots also. To cure it I drilled dozens of holes from top and from under just through the ply, injected adhesive, then refloored.
It required gutting cabinets and dinette, around toilet, any place walking weight was placed.
A good note, it sold very well all fixed in '97

Most TT floors if the sidewalls are laminated fiberglass and foam construction, have laminated foam construction floors and have been that way for at least 20+ years or more. Especially so for Forest River, Thor, etc. Some Forest River and other brands recently went to plywood floors such as Rockwood but in actuality its not plywood but OSB. The cure may be worse than the disease.


Some laminated floors last, some don't. Some are bad from the day they are laminated, some go bad from traffic from obese owners or constant use usually at high traffic areas such as in front of the sink and inside the entry door.

That's why almost every RV manual ever printed says it's designed for part time use.

Basically shoddy constructed junk almost across the board.

At the first sign of failure in my Rockwood trailer, I placed a 1/2" piece of plywood over the foam floor in high traffic areas. Removed it and dumped the trailer as soon as possible.

The wife and I were at a campground where a woman actually went through the foam floor of RV and had to be rescued.
We witnessed the rescue and need to mention.....she was well nourished.

The foam people sold it "as strong as plywood" ! At first it is but over time, it gets soft. The best solution would have been more support from underneath. Now, I have no advice.

Do a little research. From Jayco, "On top of the floor, we install tongue and groove plywood," It may only be 5/8", but they swear it is plywood. That's why my last three trailers have all been Jayco's.

I respectfully disagree. Mine was spongy from day one. Bought the new camper took one trip and came back and traded it off.

Mine was a Gulfstream Streamlite not a Forest River but same type of construction. They just did not put enough support under the floor.

Thanks for the info. Next one I will verify it has a solid floor.
