Slide underbelly materials
New to forum and want to share my experience with KZ toyhauler. Discovered last year the main slide floor had rotted at the ends or slide sides. The floor was laminated with a plastic outer layer, plastic slide pieces on the ends. The plastic had cracked and broken away in several areas. Water wicked into the plywood laminate floor and caused the damage. Likely happened over time as I bought this RV used. This slide is 12' long for living/dinning room.
I used 2x4 "stilts to hold the slide up while extended, to remove the rams and drop the floor. Build a new floor by laminating plywood (glue and screw) for 1" thickness. Laminated counter-top material to the plywood for a durable and waterproof bottom, using contact cement as you would for regular counter-top. This still leaves the edges vulnerable and so I fabricated aluminum strips to hang down just below the edge to direct water. Did not like that and so I got alum angle to go under the outside strip and wrap around the edge of the floor. Realizing this could rub on the new carpet I use vinyl flashing (doubled) for the floor ends to ride on. The vinyl flashing comes in rolls and I use a 12' length for a carpet protector, with the ends doubled. I do tape this protector down and that is a bit of a pain but worth it.
Been on the road since May this year and this solution has worked well.
Just looked at the Sanibel and really like it for the next step RV. Found this forum looking for potential issues. Been there, done that! Now I am uncertain about Prime Time!
