Give me a museum and I'll fill it. (Picasso) Give me a forum ...
If I was going to take such measures, I'd just move into my fifth wheel trailer with 4 slide outs. At least then I could move to Florida for the winter.
Wow, that is one long garage but it sounds narrow. Good for storage. Have you considered attic lift to get stuff up there more easily? Lots of examples on youtube.
We used attic trusses in our 24x28 two car garage and planned on the attic loft. The original truss design was only 12' wide and I objected and told them they could do better... expecting I would pick up a couple feet... but they came back with 16'
We finished it off and it is now DW's she-cave.
