Hard boxes / milk crates

I love the rux system but have a few use cases where I end up falling back to solutions like sidio crates or similar straight-wall containers https://www.uline.com/BL_190/Straight-Wall-Containers

Primary requirement: Rodent-proof. The main location I end up storing things when not carying around and in a vehicle is a garage where it’s proven impossible to keep those cute little critters out. They’ll crawl through anything with holes and they’ll chew through anything soft to go make themselves a home.

Secondary concern: Waterpoof. If it’s water tight, that’s great, but I’m also happy if I need to use the existing waterproof Rux bags into.

Dimensions: Love the Rux modularity. For this use case, I’d be happy either with something slightly larger than the current Rux boxed that a box could drop right into or exactly the same dimensions as a Rux box that I’d transfer the contents between for storage.
