Rad seeing similar ideas out there. We did the same but a little more minimal (as a trial). One 35gal cooler sits on the drivers side for beverages and another on passenger side for foods; both accessed by the side doors. our bedding goes in the middle while we’re en route
I need to pull it out, clean it up, and add some tiedown points for the coolers, and a little reinforcement now that we know it was the right thing to do.
Nice work here.
