16 Keystone Carbon 35 garage floor falling through

Hello everyone,
So I have a big problem and would like to see if anyone has heard or experienced it. I just unloaded the back of the toyhauler and found the right side floor right by the dove tail really soft and flexing. All I carry is an
old golf cart. Where the wheel was parked is indented in and about a foot behind that is really soft feeling. I have only had the trailer for 18 months and bought it brand new. I have attached photos for reference and would like input on what I should do in this situation. Any input is greatly appreciated and let me know if you need more info. I have a video that shows it moving as I gently step on it but it won't upload.

It sounds like you have a leak somewhere that is letting water in. Maybe a tail light or clearance light? Regardless, the floor is going to need some patching/replacing. But finding the water intrusion will be priority one.

Welcome to the forum from Kansas City, MO! Glad you're here! I wish it was under better circumstances.

You might also check the metal vents that allow vapor to escape. I left the lower one open and after a rain found a puddle of water in the middle of the floor. Also, if you have w/d connections. On my Fuzion 416 the kitchen plumbing and w/d connects to the gray water tank that I think is under the garage.

Thanks for the replies, I am pretty sure it it not the vent area. It is basically right under the window back there so I am wondering if it could be leaking internally and going under the rubber mat. There has never been any water on the top of the rubber.

Leaks are nearly always tough to find. That window would be suspect. But, someone needs to start removing panels windows, lights etc. and find it. Remember water always runs down. When you find a problem area such as the floor panel look up. Look up walls, each wall not just the closest one. The leak is normally running in the walls not on them. Unless water has been forced inside during travel. No point in repairing the floor without fixing the source if in deed it is a leak.

I understand sir, thanks for the input. This is insane on something only 1 1/2 old. And of course I am sure I will receive no help from The manufacturer. It is hard to stomach the amount of money spent and it is having an issue like this that is gonna cost me a bunch!

Have you been underneath the rig to look at that area? May be something under there that needs to be corrected. I'm assuming aluminum studs? Maybe the thin underlayment board is not secured properly under the chloroplast? That's the only thing that came to my mind. Good luck.

I have been under there and it is all sealed up with nothing that looks out of the ordinary that I can tell. I am probably just gonna have to pull the rubber mat up and see what it looks like under.

Just posted in toy hauler section. I too just found some soft spots about palm sized right where my 2016 Impact 311 garage floor meets the rear frame on the right and left side. We do have two windows in the rear but I see no signs of water leaking from them and never see water during heavy rains. I am guessing it must be running down the door frame and wicking under the door threshold and the wood is drawing it in. I plan to give it the hose test to verify. Either way I plan to seal the door threshold on both sides.
The product I plan to use is Fasco 99 Stop Rot epoxy. The Fasco product is a great product and I have used it for years in many applications. I Plan to drill small holes into the end of and inject the epoxy. I am trying to avoid replacing the wood at this time and having to replace the coin flooring which is expensive and not readily available in small lengths. I will place a few jacks underneath the soft areas to put some upward pressure that will remove the slight sag as the epoxy dries. If I am not satisfied with the results, I will replace the entire piece of wood.
I'll post up my results.

Thanks for the reply and sorry to hear you have what sounds to be the same issue. Please let me know how it turns out and what you find. I am curious if it could be that the floor was installed in the space between 2 frame supports and the weight in that area caused it to crack which is causing the flex. Either way I am planning to take up the diamond plate strip at the rear by the dove tail and cut into the rubber mat to try and see what the wood looks like. If I had to bet it isn't glued down like they say it should be and I should be able to pull it up with some heat. I will keep you informed on what I find when I get back from my trip and dig into it.
