Damn manufacturer ... of my 2016 Thor Hurricane 32N
So I notice a slight open joint on the trim at bottom of slide .. where silicone once was , had opened up... I thought , the movement has just caused it to open, no worries itís just trim ...
Upon further inspection, the screws have rusted off on the bottom side, and I could push this trim down... WTH?
To top it off.., the bottom of the slide is nothing more than cheap ass OSB board, with a vinyl covering.
Where the rusted off screws were , is nothing more than disintegrated sawdust, Back about an inch in one small place
keep in mind, this RV has been stored inside , only been on about 8 camping trips and most of water has been from washing and not rain.
Having been in the home construction business my entire life, I have to question the design... the design and material, incompetent as hell...
They could have used advantech sheathing , it could stay rained on without any damage , total cost less than $100... but dammit.. you never expose OSB to the remote possibility of water, this was designed to get wet if a simple bead of silicone failed in a flex joint.
Thank goodness I caught this, no structural problems, but with this poor design, any crack in trim creates a puddling of water on the edge of the OSB where the screws are. Had this unit been stored outside , I could see a full slide floor replacement. The manufacturer is relying on this trim joint to be the watertight seal which is a huge design flaw.
Iíll be removing this entire trim , cleaning and applying the zip system flashing tape. After that, the trim is cosmetic, as it should be.
Iíll now be doing a full inspection of every joint where water meets 2 components... gotta be proactive ... if they didnít have a clue what they were doing here... might be other places as well!
