I downsized in 2004 when we moved......from 14x26 to 6x16 starting in 2011.
Now, since the house is 20+ years old, we have been going room by room upgrading, modernizing and refreshing.....I will upsize in a 20x30 attic room which will be ready sometime in 2021 (retiring in December).
This will give me a chance to "downsize" the collection a bit.....I have stuff that I know I will never run.....and, that will go on the block.
Then the newer and smaller footprint (2011-)....
