Can you get it around a rack/lamppost/etc even with the box getting in the way?
I generally have to shuffle the bike so that the post I'm locking to is next to the fame, if that makes sense. But if I do that I can get the d locks on too. Bit of a trade off I suppose. A longer chain is easier to lock up with, but then you have to lug it around/store it. The weight wouldn't be such a problem with an e-cargo, but storing it and stopping it from rattling around can be. The chain for my frame lock sits nicely in a pouch on the inside of my stormbox.
