We kept our leveling blocks right inside the door of the hatch, o top of the plastic bin that holds the tools. Last in, first out.
We keep a long electrical cord both in the garage and in the hatch, so we always have one handy.
Bought a second 100-map battery and alsos a 200-amp one because we don't have a generator. on a recent 3-day booncock, the two 100-amps kept us going easily with power to spare.
Switched out all the interior lights from incandescent to LED - see above.
Keep the level in the cabinet where the slide-out switch is, next to the kitchen counter we use it on.
