I think this is a generally good idea. As someone who spends most of my time gathering and crafting,
To add to it,
-Local entities disappear often so, if they could be make to be "rented" from the trucking depot they could be temporarily registered to a player that could then last until storm or until returned.
-Additionally, make them a limited asset in the way Storage containers are and they can only be "spawned" from set locations.
I was going to suggest a 500 slot storage so it is not so OP but with the recent change to pounders, it would make more sense just buying a pounder as the storage space would be the same.
If it was a limited asset with 1000+ storage it would make them more sough after and/or rare
