Can I edit bank/backpack space with Gibbed's save editor?

My packrat-ness is getting to me, and I currently have 3 characters with banks just for storing items (one for purples, one for uniques, one for legendaries). What I'd really love to do is haxxor my Bank on one of those characters to be far larger. Gibbed's save editor seems to have potential but I don't see a specific option for this. I do however see a "raw" tab to edit specific data...but I also don't see any obvious way to do this.

So using Gibbed's save editor (or another tool) is there a way to modify my bank storage count for a character above the maximum you can otherwise buy via Eridium?

Solution 1:

With the Gibbed's Save Editor open with your Characters Save file loaded (Borderlands 2 must be Closed!);

1. Click on the Raw Tab.
2. Click on the Down Arrow on the right side of Black Market Upgrades (Collection).
3. Change the values for the 8th line down to 0 (Backpack), and the 9th line down to 0 (Bank).
4. (You might also want to give yourself some more Eridium (500 Max) on the Currency Tab.)
5. Save your changes, and close the Save Editor.
6. Open Borderlands 2.
7. Go to the Black Market, in Sanctuary, and buy all the newly available Backpack & Bank Storage Upgrades.
8. Enjoy. :)

If you want higher ammo capacities; replace the other values for slots 1-7 to 12. It should just about double the ammo capacity.

Solution 2:

The easiest, and only way that I know of is to use Gibbed to overstuff the bank with any bankable item, and then swap it out with what you want to keep (You must swap or you will lose the space). I think the max is 42 slots.

You can also do this with your backpack, but its more trouble than it is worth unless you never want to trade with others or purchase from machines. I tried adding slots via the raw tab multiple times but they never stay after removing an item from the bank. The slot was just gone. The game must overwrite the added slots unless there is something in them.
