I've been wanting a second battery to power my ARB fridge since I bought my Tundra. Unfortunately there isn't any space under the hood without relocating the washer fluid and power steering reservoirs which look like more of a PITA than I want to deal with, although that option isn't totally off the table. I was crawling around underneath today and spotted a couple spots that would work but the only mounting option is directly to the underside of the pickup box sheet metal. I haven't had much luck sourcing a box or bracket that mounts underneath and I don't see any place to mount it on a vertical plane (frame rail, etc). What is the collective brain trusts opinion on mounting directly to the bottom of the truck bed? My concern is sheet metal fatigue with such a heavy item mounted in such a small place.
