Hi,

I have the same model as you except mine is a 2013.

On my TT, there is about a 1 square foot cutout of the coroplast used for accessing the slide out motor in case you ever have to manually crank it in. This cut out would be a good place to poke your head for a visual inspection of the floor supports.

Climb under yours and see if you also have this cutout.

Take care and let us know what you find,

Sorry. Was thinking toy hauler. Good luck with this.

Cougar 21RBS with soft floor in the center running the length of the kitchen area. No water damage. feels like end of divingboard. deal states it is because of span between supports. Any thoughts on how this can be fixed?

There's a "fine line" between the flexibility required to keep a trailer from "self destructing while being towed" and "feeling solid when parked". The newer, lighter floor system in ultralight trailers does not "walk the same" as the older, heavier 7/8" solid floor. Also, may floorplans have a 16" "empty space" running down the center where the furnace ducting is positioned. There is minimal support through that area by design.

Some "spongy feel" is to be expected, so depending on how much you're experiencing, it may be normal. The only way to "measure for yourself" is to walk in several trailers with the same floorplan/model number and compare what you feel in your trailer vs what you feel in other models. Be sure that when you compare, you have the same conditons. In other words, if yours is "blocked, chocked and leveled" then compare with the same setup in the other trailers. If yours is "parked on it's tires and not leveled" then compare with that condition in the other trailers.

Once you get that "subjective by my feel" experience, then you can discuss it with the dealer in a "direct comparison" discussion rather than a "I don't know what's normal but I don't think this is" kind of discussion.....

Good Luck

I have a 2011 250BH that developed the "soft floor" and never had water. Started in the same place in front of the kitchen cabinets at the floor vent. In the last couple of years it has grown to nearly all of the center section of the trailer. It is a sandwich floor and I believe it is the foam core compressing and the glue failing for the plywood. It concerned me at first and now I am accepting that the floor construction is just plain failing. I would strongly discourage any purchase of a laminated foam core floor with thin top plywood. Not sure about it being laminated at all. Walls and ceilings should be fine. Will find out this spring how badly the value has fallen due to the "soft floor".

Just my 2 cents, buyer beware.

Is the only fix to place a solid metal plate or can there be some type of bonding agent injected into the sandwich board flooring to add strength?

John, dealer took off the underbelly cover and added support in front of slideout. Said floor looked great from underside. But was unable to add support in the main section because of the slideout. The spring area is a line that is 6 feet long in the kitchen going the length and dips over a 1/4 inch on my 175lbs

Have you walked inside another trailer with the same floorplan? If so, does the floor in it flex the same as your floor? If you haven't done that comparison, it's difficult to say that yours is different or that both are the same, so it must be inherent in the design. That's not to suggest it is "normal" rather the suggestion would be: If that one doesn't flex and yours does, then yours is weak. If both flex, the question becomes is it a problem or is it just something to live with. If it's a problem, then Keystone and the dealer need to address it. If it's "normal for every model built like that and has not presented a reliability issue" then it's "just the way it is".....

The first step (in my opinion) is to make a 1:1 comparison with another trailer just like yours and inspect the floor in that one for similarities/differences. Only then can you determine if yours is different.

John, we have been in others and the dealer said it is an issue but had no idea how to fix it.
