[DCARLTON]

So, we dropped our off at the dealer for Service Bulletin work for the furnace and since we had previously told them about the floor, they were going to do some preliminary look prior to contacting Keystone.

The size has grown from approximately the size of your hand to about 1 by 1 foot square where you can feel a definite break/seam/support underneath the vinyl.

We get a call from the service manage indicating he dropped the coroplast and was looking around for a broken support and didn't see anything. He then made a small opening in the Darco and said he was able to smell mold/mildew and the wood where he exposed, was able to take his finger and peal back some of the wood, indicating this is water damage. They have been in touch with Keystone, discussing with them the issue - they are now waiting on us to bring it back to them for further analysis. So far, all possibilities of how water could get to the middle of the trailer without compromising something else defies logic.

The floor is covered from the bottom and wrapped over the top with the Darco. Then the vinyl is put on the top and wrapped over the sides pretty much making the floor waterproof. However, if there is a failure in any piece of that construction and water does manage to get in, it has no way out (but it shouldn't get in right?).

I checked all roof seals, nothing. I checked slide seals - all looked good. They wondered if maybe we had driven through a lot of water, no, nothing but normal rain. They wondered if maybe tires spray could have penetrated the floor somehow but there was zero evidence of that.

Now what's the cause? Considering it is in the middle of the trailer, away from any water, the mystery deepens. The closest water is at the island sink and drains but there doesn't appear to be any leaks there nor is there any damage in that area.

As they widened their investigation, they determined that the worse area has to be the starting point of the problem and it is now wicking towards the other side of the trailer causing it to fail as well.

We had 1 more scheduled camping trip for this past weekend and we are taking it back to them this coming weekend so they can begin the tear down process to take pictures for Keystone. They have already notified Keystone of the issue and now going through the process to determine what the cause and/or fix to this problem is or will be.

As of today, the back half of the floor is very unstable with a sizeable dip of at least 1/2 to 1 inch as during their initial investigation, they discovered the whole back half was compromised. Not sure how long this process will take, at least now it's at the end of our camping season. Going to winterize it along with taking all personal items out of it, who knows how long this process will be.
