Right, that's the way to go, I wish the PO of this shop didn't want a well ventilated shop, steel siding, steel roof, but so well ventilated that the snow gets in there. Not insulated, so when I really have to be there for a longer period, I’ll just start up the BBQ on wood and with the doors closed it gets reasonable for a polar bear, the smoke is no trouble at all, did I mention well ventilated?

Putting heat in there, would take some major changes and lots of insulation that will have to come out of Truck’26’s budget. I’m not in a hurry and get my exercise anyway, it’s calving season from the middle of January till May, not my choice, but that’s what’s happening here.
Stay warm and have fun
