If Im driving the gear goes in the back in a small laundry basket in reverse order of process with everything else like tanks, fish ID books, towels, beach mat & chair, cooler and gallons of water are scattered around my small car.
I put a SUV type rubber liner in the back of my car, not enough vertical space for a tub and the laundry basket contains the sopping wet stuff nicely. Sure do miss my truck.
If Im a passenger, be it on board a boat or vehicle, I have to lug and heave it so pare things down considerably, although no one would call me a minimalist. Same dive gear goes into a Campmore mesh bag ($12.00 5 years ago) same way as in the basket, and the rest (towel, spares kit, snacks, fluid etc) go into a water proof carryall. When I boat dive weights and tanks are usually provided. So if not, such as riding with another diver, weights go into a bag and are another load to carry with tanks.
I guess it depends on the boat but the ones Ive been on; a tub would be hard to transfer on board and have to sit out in the middle of the floor. This stuff weighs enough already and dont want to add a heavy bag either. I figure if I cant carry my own gear Im not in good enough shape to be diving.
I thought a backpack would be a good idea but all of mine have been well used and no longer waterproof enough for other people to sit down in my space and drain all over it. I also got a small Otter case for the Cell phone, land camera and sunglasses after a 300# (at least) fellow sat on my backpack sitting as a place holder on the bench over my dive gear bag on the floor.
The gear bag can get tossed around and other bags like those suitcase types tossed on top. I have an AI computer with transmitter always attached so if Im concerned it goes it in the carryall but usually just tucked into the BC.
