sick of shower door problems

Our motor home has this style shower door or curtian or whatever it is called. Inially I thought it was a little cheezie, but it actually works very nicely, seals well, opens nicely, closes nicely, stores nicely, and is easy to wipe clean with my wash rag when my shower is over. It happens to fit our shower opening near perfectly so the vinyl is near straight when the thing is closed. If not so, I might have a different opinion. This picture shows how it might be trouble in the shower, taking up some elbow room.

I don't know how well it would hold up with rough kids, dogs, etc.
