Please add the legendary Five-Gallon Plastic Bucket
Some of them could spawn sealed with paint (rare)
And other's would appear empty (with/without a lid) on homes and garages.
There could even be a rare chance to find them stacked to another bucket, with no way of separating them unless you have maximum Strength.

Hat-to-Bowls
Craftable from certain helmets from the base game and mods, to be honest, just being able to turn the Hard Hats into water collectors/containers would be more than enough for me (we use one for that in my home, it makes sense to become that resourceful on the post-apocalypse).

the 5 gallaon pail would be a huge addition to it
