I also was/am concerned about maintaining a structural component to support the roof and side wall after removing the bathroom. This is part of the reason I built the wooden support that goes from ceiling to floor to cover the end of the cabinets. It is made of 3/4" plywood, so is sturdy. It also fits fairly tightly and I tied it into the wall and ceiling with some screws from the outside. I have seen these sorts of supports/covers in pictures of other scamps, but they look like they are made of white plastic.
I am no expert, but after some research and deduction, it seems like the cabinet near the door is much more important for maintaining structure than the bathroom cabinet is. That makes sense since it is next to a gaping hole in the side of the fiberglass structure (the door). It also has that metal brace at the top of the cabinet, which I'm sure is important for structural integrity. Also, if you look at the scamp
layouts from our friends in Backus, all of the layouts have the cabinet near the door. Layout #3, however, has a bunk and no bathroom closet - only a table where the closet would go. Thus, layout #3 doesn't seem to have any support for the ceiling on the bathroom side, unless there is something next to the cabinet, like I made. So....after seeing layout #3, I figured I'd be OK to take out the bathroom closet. I hope I'm right! I'll let you know if I notice any sag or deflation.
Thanks for all of the positive comments....whew, there were some days when I was wondering what I had gotten myself into! But there is light
at the end of the tunnel - perhaps my story will encourage others who are in the middle of a long project. My wife calls it my $20,000 scamp
. It didn't really cost anything near that much, but they know me by name at the hardware store. Oh, and I did finally get that marker light
