Group 31 battery in a Gen 4

Has anybody installed a Group 31 battery in their Gen 4? The battery box fit on the stock Group 94R looks pretty tight. Heard of some folks putting these in older generations. I'm looking to install an Odyssey Extreme series battery, which I've had excellent luck with in other trucks.

Physically they should fit but I doubt you'll get them connected. Does Odyssey make a group 31R?
