can't deny human nature
like kitchen cabinets or garage space... you beg/wish/want for more and bigger... then when you get it... it's not enough and you want more or bigger.
never ends and humans are never satisfied!
For me, that what I am like when I first start. But when after the first week or so. I start to slow down and think about what I really need.
Do I really need that moldy bread since I already got a bunch a antibiotics sitting at my base? No, not really. Things like that.
Ofc I'm always needing things like food, water and fuel. So I am grabbing that wherever I can find them.
As for the bigger backpack. Yes it would be nice to have but I leaned to do without it.
One way is that if I am looting a town or large building. I may set up two secure containers. One for non-stackable items and the other for stackable. You would be amazed on how much this little trick cuts down on the constant back and forth between your base and the loot sites.
your also better organized to so if a trader is nearby you can quickly sort though your loot and make a trade run.
One good tip is to wait till you are full up with loot and go up to your secure container that has stackable stuff and press R. This can quickly organize your stuff. Repack your chest. Just make sure you check your tool belt for look before leaving.
Then there's the mini bike which is both faster and carry's an additional amount of loot. Just remember to empty it before going back out, haha.
Don't forget that new vehicles are coming and we have no idea how much loot each one can carry.
