amikeren,
Thanks for the pictures. That's about the location I was thinking of using for the forward unit. 16,000 btus sounds like a lot. I was thinking more like 12,000, but I haven't done any of the calculations yet. It would seem easy to put a small outlet in the head as well, since the ducting runs right through it. I've got a few months to ponder this before I haul later this year to tackle the installation.
Many thanks for you time and trouble.
Cheers,
Jake
