Time to chill

There is a lot going on these days. I am prepping the outer shell, waterproofing, vent replacements, new fans,etc. Now I am finally getting to my first major appliance. I have been mulling over a/c units and decided to go Dometic Penguin. Not sure if I'm going with the Heat pump or not yet. It either uses a single zone tstat or the CCC (comfort control center). Dometic is really vague about their products. Either way I like the low profile of the Penguin and they both have the same dimensions regarding the roof opening. My plan is to:

1) Remove A/C (done)
2) Clean and prep (done
3)Patch the roof and make the existing opening smaller (done)
4) Fix broken rivets in the roof stringers (done)
5) bend some additional support stringers out of some scrap 5052 .032
6) make a brace for the opening out of some scrap MGP
7) Hopefully get the unit in a couple weeks and lure my friend Paul back with some Beer and Dans Subs.
I am not going to buck the rivets in the patch til I get the unit for some last minute adjustments
