The problem is the bottom of the slide has a 90 degree metal trim piece that goes from the side to the TOP of the slide out floor. After time, the sealant loosens and water can be channeled to the inside top of the slide out floor causing floor rot and delamination of the floor.
After reading this, I checked mine. Sure enough, just some minor floor separation on one side of the bedroom slide. No floor rot, but some significant gouging from the rollers that ride on nothing but a piece of fiberglass or laminate sheeting over plywood.
I also read about a guy who has designed a fix specifically for these Monaco slides (Guardian Plates) and has his own company producing them. Talin RV out of Florida. I talked to Chris the owner on the phone, and he walked me through how to take all the measurements needed on my particular slide. Very nice man that knows a ton about Monaco motorhomes. A week later, my kit arrived. Complete with mirrored stainless steel plates pre-drilled, cut and bent for my motorhome, and long enough to extend under the rollers for them to roll on. The kit included stainless rivets, rivet tool, glue, and sealer. Talin RV has videos on their website explaining why it happens, and how to fix it.
I called our friend Paul the RV Doctor to see if was available to install these. (I knew he could make quick work of this in a fraction of the time it would have taken me).
So, here's the pics. Turned out awesome. Thank you Paul.
We're ready for Trail Jam.
Before with roller gouging and slight floor separation.
After: very pretty
