Here's a couple of ideas that you can use. Some of you probably already do.
1) While parked, always leave the ends out of your stinky slinky carrier. It keeps it nice and dry in there as well as airs it out. And even if it rains with the ends open...good. I usually hose it out it out once in awhile anyway.
2) How many times has this happened to you? Someone not familiar with the screen door situation tries to get in and darn near rips the screen door off the camper by pulling on the loop. After all, it's a pull loop isn't it? Even my brother-in-law can figure it out now!
