Water splash-up on the underside during rainy day travel is a trivial factor in maintaining floor integrity. Plastic or other nonporous materials up against the wood underside is just begging for trouble. Better to let underside water-splashed wood air dry in the normal course of things. Water damage to TTs originates higher up: roof penetrations (vents, AC), roof-to-sidewall seams, around windows and doors, and/or plumbing leaks. Water runs downhill, so a soft floor virtually always gets damaged from up above and not down below.
If I remember correctly the "weaved" plastic is similar to Tyvek, it is supposed to BREATH ONE DIRECTION so moisture splashed from the road would not be absorbed and moisture from the floor and above can wick it's way out through..
In practice, it ends up holding moisture if the leak above is faster than the wicking action.
Coroplast is corrugated plastic board (looks sort of corrugated cardboard)and is often used in those cheesy signs for elections and such. It is not breathable but often there is openings in it in places for wires and plumbing which allows light amounts of moisture to eventually find a way out.
