The storage locker capacity code I posted above turned out to be wrong. It increased the storage on EVERYTHING, Storage Lockers, Fridge, Food Box, Conveyor box, etc. It was kinda cool, but after playing with it, it turned out having a large refrigerator caused lag issues when clicking on it.
Version 2 just increases the Storage Locker and is working great in the new game I'm playing. Attached DLL below. The storage size is set to 1000 tons, take it or leave it. If you want a storage mod with a capacity other than 1000 tons you'll have to compile your own (not that hard), here is the correct code.
public static class LargeStorageLockerMod
public static class StorageLockerConfigPatch
public static void Postfix(StorageLockerConfig __instance, ref GameObject go)
Storage storage = go.AddOrGet<Storage>();
storage.capacityKg = 1000000f;
