Very nice camper configuration! My only suggestion would be to skip the bedroom fan and commit to the second air conditioner. If you want a data point, our last camper was the typical polar white gelcoat with white roof. Our new camper is the tan gelcoat with tan roof. Temperature difference has been unnoticeable, but this unit has better insulation R-value and a 15.0K BTU A/C vs. the former's 13.5K. The enormous difference, however, is that it stays clean looking much longer!
Figure about 3 months for delivery.
Good luck and happy camping!
