Removing rooftop A/C unit - covering the hole?

I too plan on putting a mini split in our rv and getting rid of the two energy hogs on the roof. I plan on using plywood cut to fit the opening with plastic over it. Eternabond tape then Henry's cool coat. This gives me more acreage when I put in solar. As far as inside I plan on the best insulating extruded foam to fit. Getting a panel the same as what is used for the ceiling cut to fit the 14x14 hole. Then the tape they use to mach the panel on the seams.
