How are you securing the decking to it's framework? I'd like to have mine (just a floor in my 14' V) so I can remove it if I need to. I'm thinking of using stainless flat head screws with the contoured washers that fit the screw size. The only thing I'm wondering about is about the center areas of the floor. The sides would be fine but I'm afraid the center areas will not be solid enough to the framing. A couple screws there would work but not look too great in the center of carpeting. I'm using 1-1/2" square lumber for framing.
