How to know unit is not put together by seller?

Is there an indicator on the auction that states whether the unit was put together by the storage facility?

I went out to check a unit I won just the other day and I’m a 100% that the items in my unit was from 4 other smaller units LOL

It should say “lein unit” or “non lein unit”. A lein unit shouldn’t have been messed with by the selling storage locker company. In a non lein unit, the locker company sells a pre opened unit, maybe multiple pre opened units all put into one. As I was told by a guy when loading up the stuff from my first locker.
