Water Leak/Damage - Recommendations?

I've been pretty good at inspecting and having the roof, edges and corners resealed with Dicor Self leveling sealant, BUT, just this week I noticed a little water in the garage area of the TH when getting ready to head to TN. THe TH lists a bit to the driver side when parked and I had it slightly nose down. The water was coming from under the diamond plate on the passenger side just behind the entry door to the garage. So, ended up pulling all the diamond plate and found the damage, traced it back to what I believe is the rear corner. Looks like it is coming in along the metal frame and outside paneling then running and weeping all along the wall.

I have included some pics. FIrst one is the whole wall, 2nd one is the corner where I pulled the inside paneling off and inslulation.




In this area the outside wood is very wet. I took the small air vent out to see if that was the source but it showed no signs of leaking.
Cut a hole above that vent in corner and outside wood is still wet, concentrated in the corner.



Now I am stumped. the corner trim on the outside all looks good, no cracks in sealant/caulk. The top corner also looks in good shape, not cracks, nothing peeling or separating.



Also as I stated, the TH tilts towards the drivers side slightly when parkedin my drive, so I don't think it is coming from the garage door area since that would run the other way and not uphill towards the corner.

Couple questions?
1) Anyone else with a Fuzion had this issue?
2) What recommendations for next step?

I will say I have duct taped a piece of plastic from just under the roof edge and rain spout all the way down so that the corner trim is fully covered. This is my attempt to isolate where it could be coming from.

Any recommendations or help would be greatly appreciated. This sucks because I inspect this twice a year so this wouldn't happen.
Had the TH all the way to Montana in October thru down pours of rain with no signs of this at that time.

    Could be from the marker light too. My last trailer (2006 Mountaineer) had a bad seal under the spotlight on the roadside, when the light filled up to the level of the bulb, the water went down the wire, behind the refrigerator, across the bar and got the floor on the curbside wet. It took an experience RV shop 9 months to figure this out. After spending $3200 to fix and recarpet, the roof leaked a year later. I just traded the sucker.


    So that is interesting, I have another post here where I said I found the rear spotlight lens on that side of the back loose, ends up the screw holes had fatigued and cracked. Hmmmm.....could it be that was leaking and like you said running down the wire? I'll have to check that out. I just assumed if that light was leaking it would run the way the camper was tilted, opposite the corner that is getting wet.

    Thanks!!

    How about the seal around the window.

    On my 5th wheel the water traveled along the window frame and then down inside the wall. I noticed when I stepped in a big wet puddle in my carpet. Resealed the window and leak is gone.


    I thought about that but that small square I cut above the vent, the oustide wood is still wet there and that is above the lower window. The top of the upper window is just under the rolled up awning so I don't think water can get in there. Plus the wall seems to be the wettest by the corner.

    Maybe if it still leaks with the plastic on, I will dry everything back up and then run a hose on each window, just to be sure.
    I have been running 2 big fans and a heater in the area to dry everything out.
