Steve, ya sure the AD panel is individual planks? I know for sure both models of TF series have ply floors .... I think the skid strips in panels are foolin ya, the burbs didn't have those, but I think all series of panels & burbs have a ply floor, it's structural - sounds like TYPLE is talkin about the single sheet being fabbed - mighta been before GM was makin their own full sheets the right size, which is when there's less waste
