I think a good awning mat is a must - helps to keep the camper clean and looks nice.
A "good" mat in my opinion is made of Polypropylene, is lightweight, strong and is "weaved" to allow water and air to pass through so you won't have any puddles on your mat. This also makes the mat campground-friendly and won't ruin their grass.
