Tell the thousands of farmers and contractors that use pole barns every day to do the maintenance and build things.
As for outside storage I consider a pole barn inside storage.
And believe me the thousands of us kids that were called "shade tree mechanics" from the 50s 60s and 70s would have loved to have had a pole barn to work on our cars in. I have never had a totally sterile environment to build engines or Transmissions it would be nice but it's not necessary.
Just my opinion which I highly value.
