It would be nice if there was some storage mod for Legendary like Tom's. Right now, the only realistic option is vanilla chests, but with the sheer amount of gear and unique items you get, even vanilla item sorters wouldn't work. Reinforced chests with quark help with I stackables but they're finicky.
Iron chests might have been fine but even an iron variant costs like 80 copper and a couple hundred iron. (Technically enabled, but not really - you can get iron chests in a legacy way)
