Here's what I did with one of the two skylights in ours. I hate skylights. Both are painted / coated, insulated etc, but the kitchen one is just a little more dolled up with the LED's and such. No sun, no heat. For now, the outside is just coated with liquid roof, but the whole dome will be deleted later. Or, maybe just do a cover like OC did.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
