Nearly eleven months after it went on my to-do list, it's finally done: we've gotten our stuff cleared out of the rented storage unit and shelved in our own storage shed on the home acres.
We gave up on finding the time (and energy) to put the shelving together ourselves before calling in a moving crew, and arranged to have the movers do the construction as part of the move.
That was the biggest remaining item on our list of chores, and represents the end of a sizable recurring expense -- since those storage units don't come cheap. At last the shed is serving its intended purpose. Calloo, callay!
