I have plenty lighting, several hose reels, several cord reels, insulation, drywall, heat, A/C, storage shelves for all the extra parts. Large 220V compressor, small 110V welder, larger 220V welder, 3 hacks, 18 jack stands, tool boxes full of hand, power and air tools, beer fridge and a hoist with a winch.
I manage to get by with what I have.
The one thing I don't have that I need is a alot more room.
