Caulk or no caulk

Thanks. I figured from the stories I read on here if there was a problem someone would have already gone through it even though I couldn't think of one. We have a Genesis Supreme and they seemed to do a great build job but didn't caulk that area so I also thought there may be a reason. I think it is going to get a good fill in a couple of days.

Oh got it. It’s not a cover plate that’s screwed down.
Then yeah I’d fill it full and wipe it clean so it’s not exposed to traffic.

I don't believe he's talking about ramp doors, but rather the floor inside the trailer.
But...
Do TH ramp doors typically encapsulate material that is prone to rot?
I never considered that having owned multiple other enclosed trailers with ramp doors that literally got wet regularly/constantly for periods of time with no issues.

Not something I had considered...a toyhauler with paper mache ramps?

Yes I am talking about where the dove tail of the floor goes under the plate at the back of the toy hauler. I don't think I can remove it as it is welded to the frame.

I was thinking about caulking it under the edge as there is a gap between the top of the floor and bottom of the plate.

If you're actually getting a significant amount of water on the floor, then I'd say you're tracking straight, however I'd consider something else than caulking the surface.
It's a sill plate screwed down where the floor goes from flat to dovetail, right?
Remove the sill plate and either caulk under it and compress it back down (hidden from view) or seal it with a gasket maybe. Thin 1/8-1/4" thick neoprene or similar.
Both should be 1 and done. Caulking isn't meant for high traffic/wear areas.
