I have a 30ft 1993 Excella 1000 Classic with rear bedroom and have modified the bathroom to fit my larger than average size.
I removed the wall next to the commode and installed a petite hinge the entire length and re-installed. I then install a slide lock at the top to hold the wall closed so the bedroom door would shut to the bathroom. I also repositioned the curtain to angle to the corner of the wall and installed a plug stop so the door would hold in the open position against the cutain bar.
I also moved the commode to the left by one set to allow for better leg room.
When the wall door is open and the bathroom door is cloed to the bedroom I have much more room for showering and using the facilities.
If anyone is interested I can post pictures upon request.
