I have a minimal two car garage, and long term want to keep one car in the garage, the other on the street. That means I have to use all surfaces for storage and whatnot. Not fully there yet, but keep working at it...
Main pegboard, wall trays...need to hang more tools. Also have a Craftsman rollabout tool chest.
Empennage pieces suspended from ceiling with old firehose.
One of the two approx. 20x35" rolling benches for power tools. Other has drill press & belt sander.
