Largest 12v cooler/fridge that will fit in cab?

Currently doing research and such but thought I'd make a post, wondering what firsthand experience everyone has with a 12v cooler/fridge in the rear of a double cab? Whats the largest unit that will fit? I've removed both rear seats and am fabbing a floor/rear wall.
Thanks for your input.

 

Iceco aluminum 19L fits with just folding the seat bottom up.

With the seats out can easily fit a snowmaster cl56D or national luna 50-60l fridge probably much bigger if needed.

 

You can fit some pretty big ones but the issue becomes opening the lid and having space or anything else. If you wanted the entire rear cab to be fridge I guess you could.

I used a 35 because I could fit it behind the seat and still have 2/3 of the rear for other stuff. You could probably fit a 60 or 80 as long as you can get it in the door

 

ARB 50L has spent a lot of time in my rear seat, just on the seatback folded down. Can't open the lid all the way, but it's never been a serious issue.

I don't see any reason my Dometic CFX75DZW wouldn't fit, it would simply take up more space.

Don't forget to leave space around the vents for air flow. Can't just pile stuff solidly around it and expect it to work.
