We use the Stormate garbage bag holder by Thetford. It holds a 13 gallon or larger kitchen trash bag. It collapses to a small 2" tall nearly flat square, very easy to store when not in use. It also has a lid, thereby keeping bugs out.
As you can see in the photo, we use a large rock placed on the base to keep it from blowing over. I recommend this neat bag holder to anyone tired of tying their bag on awning poles or dealing with flies and yellowjackets that love to hover over trash.
