Loc: Oley, Berks County, Pa
We looked at the a few years ago after being eaten alive in jersey. There are many to choose from. Some have bottoms, some don't. We even came across a few that attached to your awning and had sides and a front with a door, then shorter pieces for the side the camper is on.
Decided to stay in Pa where the bugs aren't as bad.
Really need to get my blogs back up to date
