I have 10hr drives and ferry crossings (each way) for much of my diving if I want to see any wildlife or good viz under water.
Regs are on the tanks, scrubber isn’t packed, but everything else is ready to go.
2 Rubbermaid half height bins, one for BP/W/Harness and related equipment (lights, reels, canisters, etc) the second bin has my drysuit with fins (and any drysuit accessories.. weight belt, fin keepers, pocket stuff, etc).
Gear stays wet until I get home for proper soaks and cleaning. But will used freshwater when available at dive sites along the way.
DPV on cradles, smaller batteries in my undergarment duffel, along with some oh crap tools.
Chargers in a small shoe Rubbermaid with a very similar USB/outlet station that RJack posted (can find them in 2packs at Costco) 6ft extension cord and away you go.
Multiweek trips, all maintenance tools (except for the meg and ultrasonic) make its way in another tub... usually someone else needs a little TLC adjustment)
