You've seen the posts about installing a small home window unit in the
center window at the helm, right? Doesn't give you A/C while running, but
works great at the dock or anchored, and costs $100 or so. If you buy
one, spend the extra $20 and get the one with thermostatic control. See the
photos in my album for an exact model that fits. Order one online
from BestBuy. If they mess up, like they did for me, they shipped directly
to my house for free. Anything that saves a drive out where Best Buy
is great (nothing against the store, just Delaware traffic).
Bob Austin (thataway) has notes on what the startup draw on A/C unit
like this is and what it would take to run it. Check his posts, but I think
the 1000 watt Honda will do it.
As to mounting... well, the basis of my post is A/C while not running, so I
would keep the genny in the cabin somewehere. We keep the A/C in
the V, as shown in the photos. When running the genny, probably put it in
the splashwell.
