Thanks.
The bathroom door itself would normally cover the rear door when the bath door is opened, but we put an over-the-door towel holder on it (facing outward) since there was no place for towels. As a result, the bath door won't open fully to cover the rear door. That's not a problem for us to get in and out of the bathroom since we needed the towel holder.
As for the dressing area curtain, I saw that some more expensive Trail-lites have a little folding door there, along with leather seats and other niceties which probably added $20,000 to the price. :-)
