Sorry this response is so late! Don't know why I didn't get a message alerting me this was in my file. Anyway, the screen room was one that came from Escape when we purchased the trailer. I understand that the new design does not allow for these any longer which is unfortunate as we really do use our screen room quite a bit. (Not every time we set up camp, but it's usually with us every trip.) While camping in Northern CA earlier this year, we arrived at our camp site in the Redwoods only to be attacked by mosquitoes. I had to hide in the trailer while John set up the screen room as mosquitoes love me and not him. After it was up, I sprayed the screens with bug spray and didn't have a problem after that. Plus, it really does work well to keep our dogs in ... but they tend to stick around anyway.
