I guess the OP has been advised about the various levels of storage that are available, from open space, uncovered to concierge wash-your-vehicle while you're gone. I'm thinking Ames, IA customers will want either enclosed garage space or an open space parking spot.
FWIW, my BIL moved a large pole barn (approx. 140 x 80) to his property many years ago. We, as BIL's in the trades, helped him disassemble the building and re-erect it on his property. This shed is typical machine shed construction. He rents space inside the unheated space for RV's, boats, and cars. He has a waiting list and has some folks that have never moved what they park but continue to pay the annual rent. It's not a bad way to make some money if you can endure the calls for patrons to move their vehicles out, when needed. He does all of the moving.
