Hi,

I want to add AC/Heat to my boat. (1942 80 ft. long) Previously it had
motor home style units installed in ceiling.

Is this the best way to go?

I get opinions from home style AC mounted to cabin roof, motor home style to
marine AC with water exchanger.

What advice do you have? I am leaning towards the marine style and if I
choose this approach then I will have a second question...one large unit or
several small units?

thanks,

Marshall
