I went to some specific areas to see if I got all the loot what would i potentially get. This is just one run but given you might spawn and be first to some of these areas it gives you an idea of what to expect if you do a full clear of all loot (internal stores I did not open crates except kiba)

Here is what I found:

Power station area (everything looted):

All back warehouse areas across mall (idea, oli, gosh all toolboxes and crates): https://imgur.com/a/5vbzule

Safe room (all boxes): https://imgur.com/a/egjX2TD

Killa loot crate: https://imgur.com/a/uq0f6MJ

Next thing I will try to test is go to every store and see what I find in just the interior mall stores. Hopefully to find out if maybe other stores I or others might not go to have more or better loot. At least from this it seems like looting caches might be the way to go if you want to make some cash.
