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.

I'm thinking that Group 27 batteries may be the way to go. They should fit and Odyssey makes the Extreme series in the 27.
