Can't say as I have, but, I have heard of people getting rid of solid enclosures and installing the "wide angle" shower curtain bars. The solid enclosures tend to be restrictive; read you are constantly bashing elbows (and other parts of your anatomy) into the rigid walls and let me tell you, that gets old real quick...they don't give an inch and the door if you hit it just right, will pop open and soak the floor just as quick as a shower curtain. I've got one (rigid) in my new 5er and, to be honest, if the campground's showers are in good shape, I use the campground showers just to avoid the bumping and banging. It doesn't hurt, just annoying. I'm not even a "big man", only 5'6" and 148 lbs, but, I find it very restrictive. I've got another big project going on right now, but, I'm considering getting rid of my rigid for one of the "expander" type curtain assemblies. Oh yes, did I mention that you have to remember to "lock" the door closed before hitting the road or it will beat the daylights out of your sink's vanity edge? Don't ask me how I know...
