RV Repair: Underbelly material, 5th wheel, holiday rambler

Question
The underbelly material on our slides on our Presidential Holiday Rambler 5th wheel have come loose and split and all 3 of my slide undersides need to be replaced.  Where can I find that material?  It is all white probably 1/16 inch thick or so and looks to be maybe 8 foot long.  It is solid -not corrugated- and seems to be somewhat bendable. It looks like it might have been glued to the plywood. (This is the material between the ground and the base flooring on the slide)

We have asked several Big RV places in Texas about this and they look at us like we have 3 heads.  This can't be that hard to fix if I knew where to find the material. Is this applied with an adhesive?  Best way?  Any suggestion?


Answer
Suzanne, You should be able to contact Monaco and get the material you need. As for how is it attached, well I haven't had the need to replace any before of theirs. They make a good coach and about the only thing I have ever done for the slides is to attach some plastic under for runners and I countersunk screws to do that. I hope this helps, Bill
