Recovery straps, d-rings, quart of oil, quart of ****** fluid , brake fluid, jumper cables, flash lights, all under rear seat ,
first aid kit under drivers seat along with gloves,
water, snacks, extra hand sanitizer, other hand cleaner under passenger seat
blankets, tools, another flash light ( all needed from minor repairs to almost complete rebuild in tool box and tool wraps in back )
Then most days two foldable chairs and a metal cooler from the very early 70s ( this doubles as storage when not filled with " liquids "
and still have space to put grocery items when doing what a KJ does ( grocery getter )
That's most of the junk I carry , tools etc that are in the back go to whatever KJ I am driving , rest is in all of them
