Yea there has benn a lot of great feedback but nobody mentioned a tarp. One of those plastic tarps is not going to work. You need a woven trucker tarp. You can usually find them at larger nursery's or landscape supply yards. They usually have a smaller one for pickups. It should hang over the sides almost a foot. Most guys use a bungee cord to eye hook setup but I have always used 2 foot sections of rope tied to the tarp.
