this is the left roof interior. originally I was going to have these side roof panels slide open at the top, but that is a 90 degree angle. by placing the handles and having them open at the bottom that is only a 45 degree angle. The outlet was at the top for a center 110vac light, but I decided that with the end 12v spots, and I'll put in individual led lights (4 or 5 variable brightness) that I don't need the light at the top and the cord(s) for any thing else would just get in the way. (One of the outlets is on a 3 way circuit with a switch at the front and rear left side.) I am planning on cloth loops of velcro on the panel guides for attaching things, and screw in eyelets in the corners for heavier stuff (so I don't loose my scalp hitting an eyelet then will be in the corners so my fat head can't reach. :-) This is also your first view of the ceiling registers installed.
