We have designed a simple yet effective solution to mainting air flow under your cover and deflecting hail from the sides of your RV. Chains of swimming pool noodles are created by threading a rope through the central hole of the noodles. The pool noodles provide a 75mm air space between the side of the van and the cover fabric. This innovative design will reduce the radiant temperature underneath the cover, reduce build up of humidity and deflect hail from the sides of your RV.
