Floor issues, do we keep the membrane?

Thoughts please, we are ripping out the completely rotted floor from out Roo hybrid, it's a typical sandwich construction. I'm hesitant to keep the membrane, seems like all it does is trap moisture. Obviously this unit had some major leaks, but my older popup was built with just sealed (painted) plywood over the frame and the floors are in perfect condition. I hate to "seal" in future possible leaks again. The underside of the sandwich was much better than the top.

I guess if it were my camper, I think I would put it on the top side and wrapped around the edges.

Chances are high any leak you may have in the future is going to come from above. Floors rot from either the top or from wicking from the sides generally. Rarely from road moisture as traveling drys them out from the heat of the road and wind. I've seen plenty of unprotected plywood popups that had great floors after 8-10 years. Most of the ones I've seen with soft floors were from a roof leak that traveled down a side wall and rotted out that wall and the floor section near it or from a plumbing leak that went undiscovered and unrepaired for an extended time.

Just my 2 cents.
