Last kitchen update for some time: I got the ABS plumbing figured out and the dishwasher reassembled, and my brother came by today and finished the heating duct in the crawlspace and fitted a plywood floor. So, it appears I have a fully insulated crawlspace and the kitchen is again a kitchen for cooking.
I still have some cleaning and dusting to do but it is a much more manageable space again. Thanks Bro!
I see progress!
Snails pace!!
