Front Corner Separating

Rockwood Roo's and Flagstaff Shamrocks are the only hybrids that have laminated ends. The outer layer of that front panel, the fiberglass and luan, extends past the foam and inner panel at that corner. They then screw through that into the sidewall panel and those screws will be visable when the corner trim is pulled off. They don't use many screws there, and that is all that holds the corners together. The OP may get lucky and all that has happened is the screws let loose from either not enough of them or they were stripped when first assembled.

Thanks for the suggestion. I'm gone for a couple of weeks, but I'll keep you updated when I get back and can look at it...

I'm sure you'll see the issue when you do that....

Thank you for the information. I will keep looking and let you know what I find.

I had a chance to look at a 'Roo' just like yours today, was in the driveway next to a friend's house. I'd say the water is coming down from the seam in the front. It'w water intrusion. The obvious sign will be if you pull the vinyl trim that is inside the channel (don't worry, it's replaceable and if you rip it, you can buy it by the roll online and it's cheap.. and look at the screw heads that secure the aluminum channel. If the heads are rusty, it's water intrusion. If some are and some aren't, run a few out (you'll need a square drive bit for your drill motor) and look at the threaded part. If the threads are rusty, that will confirm water intrusion. Another telling aspect is the color of the material under the Filon siding. It's dark brown, very dark, a sure sign of water logged wood that has swollen and pushed the trim piece away from the side Filon. The wood should be light brown, not dark brown.

Kinda surprised it's not showing inside on the wallboard, but then, I don't know exactly how the trailer is built. If you can use an inspection cam, all good but if you cannot, an IR non contact digital thermometer used inside will tell you. Shoot the same side wall away from the corner and note the reading (don't matter what the outside temp is), and then shoot the suspect corner. If it's water intrusion (and I think it is), the corner in question will be a few degrees warmer than the wall away from the corner because the water causes mold and rot and they produce heat and the IR thermometer will detect that.

If it is water intrusion, and you aren't real handy with woodworking and fiberglass, I would suggest having it professionally remediated. For one thing, most mold that grows in there is toxic and Filon is very hard to work with plus you'll need to replace some of the structure and it's no easy job.

I liked it much better when RV builders clad RV's with aluminum sheet. Easier to deal with....

For your sake I hope it isn't soaked, but I have a feeling it is.

I've seen a lot of used campers where owners have attempted to cover up water intrusion, from painting interior wallboard to filling gaps with caulk but underneath mold and rot never sleeps.

Wishing you good luck and a dry underlayment. Let us know what you find.

It's pretty easy to remove that corner piece, then take more photos of what you find. It should be rather easy to poke around and find any rot with the edges exposed.

Agree that it appears that water has infiltrated that seam, probably from not re-sealing that seam or it's coming in from the roof seam.

The wood in the filon has got soaked and swollen.

Is your Roo a hybrid or a rear bed slide TT? That curved front looks different from a hybrid.

From the looks of it, I'd say you have had a leak and it's the result of water under the Filon and it's probably rotten too. How about a front picture as well? In as much as I don't have one, I'd suggest getting inside the unit and having a good look inside in that corner from the floor to the ceiling and see if there are any water stains on the wallboard inside and at the point where the floor meets the sidewall.
