OK, here are my two Aluboxes from Paul May at Equipt Expedition Outfitters, the 60 liter one showed up yesterday.
I am very impressed with the high quality of these, so light, and waterproof and dust proof.
Going to use the 60 liter one for my dry foods, and also to keep the Aeropress coffee maker and Magma cookset in.
I could keep the latter two in my chuckbox just fine, but but trying to keep the weight down of the chuckbox when I carry it from inside my place out to my rig.
When I get setup in camp, those two items will come out of the Alubox, and be stored in the chuckbox.
Back in my younger years I would have no problem lifting the heavy chuckbox filled with everything, but now as I approach senior citizenship, I have to watch what I lift
The smaller 42 liter one will hold all of my Goal Zero LED camp lights, the Powerfilm foldable 60 watt solar panel to keep the starting battery topped off, and various other solar items.
I will still use my ECS footlocker to keep supplies in.
But the ECS cases compared to the lightweight of the Aluboxes may make me get a bigger Alubox in the future to replace the ECS footlocker.
The only thing with the footprint of the Aluboxes is they must be the same size to mate the four corners too.
With the ECS cases being like Legos, you can mismatch case diameter sizes, and they will still stack and interlock with each other.
Here they are side by side.
60 liter on the left, 42 liter on the right.
The two of them mate together with their corners, and lock to keep them stacked nice.
On Christmas break from Boeing until January the 3rd, so my guitars all come out to play with.
