No progress?
Too cold, or did it drive off?
Got a real job.
The last of the progress was completed by the BIL. He had somebody give the wiring a cursory glance and we tested the AC wiring without killing ourselves so we declared it safe. We ended up swapping over the switch circuit so the AC would reset to shore instead of battery when there was an interruption. I'd wired it according to the instructions but our plan and the master plan differed.
Solved the gas leak by tightening some itshay up.
Closed up all the cabinets and now I think his only concern is that the ittshay little electric space heater runs too hot even at its lowest non-thermoswitch setting and he needs one which auto switches the element off and on to maintain room temperature. The furnace works like a charm.
He's actually very close to chucking in his rental lease and moving into the van completely.
