dual battery setup

Hi all, considering selling my hummer H3 dual battery mount tray. It’s in mint unused condition. Will come with some wires and clamps. I’d rather give the people here first dibs so anyone interested let me know.

I finally got around to installing it, I still need to get a second Odyssey dry cell battery, just maybe smaller then the main one, but for now, I reinstalled the stock one in the alternate location. You will see I reused my stock battery tray, as Scarsman from Knight Metal Works made me a kick...
