I did something similar in my rear bath 78 Royale. I gutted the bath and installed a 32" x 32" shower pan and used prefab shower walls from Home Depot. I also used a shower door that slides into a canister so it does not take up any space. The large shower forced the toilet to be moved to the sink area and the sink was removed. The toilet has a 10 gal holding tank directly under the toilet (it is the base for the toilet) which allowed me to remove the black tank from under the rear of the coach. My plans were to install a pullman type (fold down) or a swing away sink but I never got that far.
I also installed a pocked door between the living area and the bathroom.
Since the shower drain is at floor level, I installed a marine type shower sump directly under the drain. The sump has a level control and a 12V pump. When the level control (float) senses high water level it turns on the pump and water is discharged into the grey tank.
When the shower is not in use it can be converted to an extra closet and storage area.
I am not at home right now so I don't have any pictures. I will have access to the pictures next Wednesday and if you are interested I will send them to you. It is part of a powerpoint presentation.
BTW the coach is for sale cheap. The motor is not running very well so I recommend that it not be driven until the problem is fixed.
If you live in the San Diego area send me an email and I will send more information.
Need it gone ASAP. First $1500 gets it or I will have to part it out.

A,
I'm not Joe, but I am looking at a 4'x8' sheet foam board product with a foil facing called R-Max, R-Matte plus 3. Available from Lowes and Home Depot in 1/2, 3/4, 1, 1 1/2 and 2 inch thickness.
1 1/2 thickness will fill the cavity between the trusses ( if you remove all the OEM stuff first) and will supply an R rating approaching R-10. This is the best R rating for the thickness I have found in various insulation products.
I have removed the oem insulation from the ceiling and hope to start installing R-Max and new headliner this week. Unless some one on the net can supply a good reason not to use this product.
The foam is POLYISOCYANURATE- probably causes cancer in rats.
Any one have any comments, questions, or suggestions?

I wonder if two layers of 3/4" with the foil layer of the top sheet facing the roof and the foil layer of the bottom sheet facing the living space would reflect heat out (up) in the Summer and heat in (down) in the Winter.

I wondered the same thing. Someone smarter than I will have to answer that.
I have asked questions about insulation in the past- get numerous opinions but no definitive answers. But almost always learn something new; sometimes even useful.

Joe,
When I redid the X-Palm Beach my son now has, I used FRP for the ceiling.
It worked well, but it does lack rigidity. Even on the relatively short
spans between the ceiling ribs it tends to sag. And if you mount a
fixture, such as a light, to it with no other support, it WILL sag. It
certainly has the advantage of being impervious to any leaks, but there are
other products with that feature. Neither my son, nor the others I've
talked to who used FRP for the ceiling complain of noise reverberation, a
concern I originally had.
I used melamine coated Masonite tileboard with the melamine up and
headliner material glued to the lower side. The tileboard is relatively
heavy so I would probably have used one of the lighter weight plastic
boards now available if I'd known about, and could have gotten them.
In my X-Birchaven, where I used FRP in the bath, it's laminated to either
tileboard or plywood; that works really well.
