Rebuilding a slide out.....sorta

Hi all,

I just purchased a new to me 39ft Pilgrim 5th wheel. I got what I feel is a stellar deal on it because it was in a lot and a vehicle next to it caught on fire. There was some damage to the DS front in the area of the bedroom slide. For the most part some of the seals melted and some heat damaged the underside of the slide. All of the damage is for the most part cosmetic. Point being I already have it and aside from that the unit is almost pristine.....plus the price was absolutely right.

Anyway on to my question......The bedroom slide floor is a 1" thick piece of OSB that appeared to be laminated with something on the bottom (think a type of formica). It probably was originally parklands 'Duro-Slide' or something similar. My original plan was to replace the floor with new wood but after examining it I don't think it will be necessary. There is some minor crazing on the bottom and the veneered finish is gone but it didn't get deep at all. No structural compromise at all. My thought now is as a preventative measure to treat the floor with something like the "Rot Doctor CPES" or something similar then put a plate on the underside of the floor using either 1/16" UHMW plastic or very thin aluminum. I am doing this because the only problem I see so far is when the slide comes out it rides on 2 nylon pads that travel across the underside of the slideout when it is in motion. I thought that by putting this plate or cover over the underside (maybe with screws or with adhesive) it would A) protect the underside where it was burned. B) Strengthen the floor somewhat. and C) Give the pads a surface to ride on. There should be no clearance issues if I use 1/16" thick material.

What do you guys think of my logic??? What material do you recommend??? Any alternative suggestions?? (besides the usual...take it to a dealer)

Thanks,

Steve

    I had to rebuild the whole bottom of my bedroom slide. I used a sheet of hard plastic made for shower stall walls from Home-depot for the bottom skin Recommended by my local rv repair shop. So far it works great for over a year now.


    That is an interesting thought. My only issue with using plastic or UHMW plastic is how to attach it to the floor with the expansion and contraction that plastic has. How did you attach yours.
    I used liquid nail glue down the center and screws around the edges with the angle aluminum that was used from factory. That way it holds in the center and lets it move a little on the rest. My rv repair guy has used this on dozens of repairs. Mine has not so much as scuffed in over a years use.

    That thin shower stall wall material should be fiberglass, which would be good.
    What I used was a hard plastic. Really stronger than the very thin fiberglass. You can also use screws to attach as they will countersink flush into the plastic.
  • Well I just scored a 4'X8' piece of FRP from Lowes for $15. It had a small tear on one side. Figure I can put the bubble side up against the underside and let the smooth side ride against the pads.

    Use a piece of rough sand paper on the bubble side and clean with alcohol before using glue. It will stick much better.

    I replaced the floor of my bedroom slide with 1 inch thick marine plywood. I used the original floor as a pattern, cut it out and sanded it. Then I put several coats of spar varnish on all surfaces. Then installed the new floor. Preparing the new floor took a few days in order to give the spar varnish time to dry. Installing the floor was a one day project. Much easier than I thought it would be.

    This was done in the spring of 2012. I have used the camper many times since then and the floor shows no signs of wear.

    I also sealed the bottom corners with eternabond tape and trimmed it so it would not land on the delrim blocks that it slides on.


    Where did you find 1" thick plywood?? Would it be just as good to sandwich 2 sheets of 1/2" Marine plywood together??

  • I bought it from a hardwood specialty store in my area. I originally planned to use two 1/2" pieces sandwiched together. When I called the store to inquire about the 1/2" plywood and what I planned to do, they told me they could get 1" marine plywood. They ordered it for me. I think it was about $150 for a 4'x8' sheet.
  • 3M5200 a polyurethane will work for this application. Available at Lowes and HD. More $ than liquid nails but much better adhesive.
