We do have a boat air conditioner on our sail boat which we haven't tried out yet which was around $500 and I think we bought it at West Marine last year. It is compact, however, and just needed a small hose for draining, easy on a boat but not that hard for our 1973 Lovebug. I was planning to run it into the closet where the furnace
is that I want removed. I'll probably put a sliding shelf on the floor and then slide the unit in when not in use.
I'll let you know when I try it out.
Do you have a generator
? That's on my list now as well. I think if we are out on the boat for a few days we will definitely need a generator
would be so great, but I don't know if that's really an option for the boat or the camper.
