The lady at RV supply store had suggested that I purchase only lights that could be attached flush with the ceiling. That was good advice; but, I was so dazzled with this one set of lights that what she said didn’t even register in my mind and I ordered them anyway.
These lights require holes to be made in my newly attached ceiling skin to accommodate them. I thought about making platform boxes for them but didn’t think it would look right and it might have caused some performance issues. So, I decided that, if I was going to cut the ceiling plywood, I might as well do it now, before coating it with urethane. That way, if I goofed, I wouldn’t have wasted urethane or as much effort. Talk about being a chicken!

It took me two days to think about how I would do it and to get up the nerve to make the cuts! I cut only as much as was necessary to allow about 1/8’ space between the area where the wires are and the plywood. However, I have wood boxes built into the ceiling framework so that the lights will have their own dedicated space.
All the ceiling lights have been cut in and fitted. The little single in the corner is for the middle-of-the-night porta-potty.
