A good idea,
we use a portable unit vented out the front driver window with power from a cord I drilled thru the slid floor under the couch, thru the floor and storage bin floor to the 20a on the power pedestal (no extra breaker added).
Take a look at this thread for
several things you can do to make the roof unit much more efficient. Sounds like with 2 units and 120* you'll need to do a lot of these cheap and easy day's
A long and very worthwhile read
