For those of you that want to protect your flex-air, trail-air from the elements we have found that a smoker/fryer cover works well. We purchased one from Amazon that is well made from heavy material. (see attached pictures) This cover has a drawstring on the bottom that will help hold the cover on, and air vent pockets made in the side for ventilation. The size we ordered for our 18k flex-air was the medium size which fits nicely around the king pin, and pin box.

Nice idea. Thank you for sharing.
