Is this rear end separation?

[Bex]

Just got the trailer home and have started the process of clean up, sealing and general bits and bobs.
I new there was some water damage in the rear floor only (and only in one small area).
I cut out a piece of the floor, stripped out the rotten bits of ply from under the wall and when I did so, I noticed light coming in from outside.
I jammed my screwdriver through to get the area of the leak from outside.
Is it separation? I would think not because its just one small spot.
If it is, whats the fix?
If its not, whats the fix? Vulkem?
Pics attached.
Thanks

Yes.

Probably need to pull the interior panels and check to make sure you have fasteners, that the channel isn't broken and you will need to add some additional hold down brackets to the channel.

How do I seal it?
Can you (or anyone else that is reading) point me to an info page or how-to?

Thanks so far

You can start by checking to see if there are still bolts coming thru the rear frame member. Feel around on the bumper box side or look to see if you can remove some screws and drop a portion of the center bellypan section and take a look. If the bolts have rusted away, you will need to get behind the wall from above to put in new bolts. If the frame has rusted away or the floor rotted, its going to be a project. Better to fix it than just plug it with Vulkem.

Bolts are there and in good condition really.
The frame area that I exposed has surface rust only, not bad at all.
That being the case, would I "just" fill it with Vulkem?
The PO disconnected the water inlet and plugged the hole in the floor so I will be dropping the rear to re-connect it. I shall take a closer look at that time, probably this evening.

If the ply wood is rotten you will have to cut and replace it. Mine was rotten out on mine. I had to replace the whole rear end plywood which meant taking out the whole bathroom. Good thing i was remodeling.

It's not a fun job but if you don't do it it will cause more damage. Like everyone has said look for some bolts coming down. You have to pull the bottom panels on the inside to get to them. That means drilling out the rivets that hold those panels on. Once you have those off you can get to the channel and put new bolts down through the flooring to suck it back up. You will also need to take the underbelly off to get to that side. It's not a quick or easy job... I didn't detail mine but you can see a picture here
