To OP...looking very good. People seem surprised...but really nothing new.

I once went and looked at some Rush the Rock driving arcades. The guy and his wife were living in an airplane hanger with an RV parked inside that he used for his sleeping quarters/trip taking. He had a steel “upper deck” platform (call it a second floor) that had living room type space, dining table, etc. and overlooked the main floor below. The main floor was his toys (plane, couple old cars, Pinballs/arcades, workout area, and workbench).
So...the next time you see a steel building just sitting off in a field somewhere, there could be one badass living pad inside.
