Roaming Hobo

You found ONE room like this am I correct? I've found several so far but that seems to be the problem. Loot is spawning but only in a few random places while every other building has nothing. I've found a house that might as well of been a super Wal-Mart and then every other house barren. I've seen a prison like that and a firehouse also. Got two protector cases off the same self and another on the next shelf. Have yet to see a barracks do it but I'm sure there's one somewhere. Loot isn't really "too abundant" just not spread out properly.
