The closest I can zoom on the bottom left makes me think I can see 150qt... is that what it is? Also, how much was it going for? I personally capped myself at the 48qt Igloos.. I had a 100qt Coleman but I was digging too much and it was a pain moving it around as much as I needed.
I saw somebody on here once with 3 white coolers on a mount he built for them.. the bottoms were basically fastened into the wall so when the lids open they essentially work like a tray. You can dink around easy and manage your stash while making use of the lids like trays.. pretty cool idea.
I wish I could remember who had that set-up.. I only saw the pic of it that one day....
