Success, I was able to go from two of these ECS cases to just one to pack in the rig now.
I had stored some stuff in the second one that I can fit behind the drivers seat easily, and some of the stuff can go inside of the chuckbox.
Here is the case with two upper trays in it holding the LED lantern, baggies and garbage bags (which may fit into the chuckbox too), sunscreen, insect juice, batteries, rope, misc stuff.
With the trays out there are the bath towels, some hand towels (may take them out as I have a few new ones inside of the chuckbox also), MSR water filter inside of the container to refill up a water jug, Zodi shower, propane for the lantern and Zodi shower, propane lantern, BW (self explanatory), that new dish drying gizmo I bought in its bag, and a water sack and a water carrier/sink (the yellow thing), have had both of those two items since my backpacking days a few decades ago.
This will save me a lot of room and I will be able to carry the water jug (going back to an old one I use to use long ago (
Reliance Aqua-Tainer), so no more battery pump one on the water cooler type bottle) and the 11 lb propane tank on top of the ECS case and strapped to it.
Should have room for the Cabelas lounger, folding picnic table, and maybe some other stuff I carried up front on the seat like my duffel bag.
Either way only one case to take out of the rig now instead of two.
Some big items I simply refuse to leave at home like the
Cabelas lounger.
Once you kick back in one by the campfire at night, the other chairs out there do not compare.
And I did pick up a second one too, only in regular size so it is 4" narrower, so it will fit in the rig better.
Instead of hauling that
deluxe Cabelas table I bought a few years back, I can probably leave it behind and just use
the picnic table to set the chuckbox on top of.
