Any FBTS owners know what this is?

Just noticed this on my floor. It is raising up the vinyl for a few inches around it. Currently at an RV park, when I get home I will cut the vinyl on an angle to see what kind of fastener it is. Pushing down on the vinyl it feels to be a big ass round headed screw. What would that go to?
Any owners of this model see this. Gonna send a pic to Jayco after I cut the vinyl to find out what this goes to. And there is another one about 18 inches over starting to come up. U can see it just starting to push up the vinyl.

It is a screw backing out and is a fairly common issue. I had it happen but it was in my pass through storage. I slit the vinyl enough to get a screwdriver in and drive it back down. It backed out again a short time later. I removed the screw this thin and used loctite before putting it back in. Never backed out again.

Fairly common, and not model specific.

I've seen screws and staples as well as construction debris through the years.
Easy enough to repair and after time you'll be hard-pressed to find where you made the repair.
