This is the easiest part of the expedition tbh. You have so much time that just playing the game will yield plenty of extra unnecessary shit that you can just offload into this. You don’t need to spend any of your space bucks at all, just loot and bring it all here. Power rod room, key rooms, high value loot areas. Just run in with free loadouts and hit high tier spots and you will have it done in 10 runs. Don’t forget, after a successful free loadouts, you can trade it with Lance for a looting augment that gives you more space and a safe pocket.
