I am also looking to add a Marine A/C with reverse Heat. I scanned the threads for details but came up a bit short.
Finisher,did you actualy install one? If so how did it go. Marin aire ,webasto and Dometic seem to be the top players.
I will be running 110 v shore power and maybe a Honda eu2000. Sounds like 8,000 btu's will cover a 282.
Any input is most welcome.
