I have done the driving thing, using a black Rubbermaid tub. Similar in shape to the Bato bucket. The problem, is leakage around the lid. Any container with a secure lid, could be used. I've seen a few versions of 12 volt washing machines, using a windshield wiper motor. They go back and forth in the same manner as my machine. Every example that I found, was using a round bucket, stood upright. The tub tends to move, while the clothing inside remains relatively stationary. When put in the configuration I have used, the water sloshes around with every movement.

Out here in the West is not uncommon to see Igloo or Yeti cooler in the back of the truck bed. They are doing their laundry! Load the clothes, add warm water then detergent. Lock down the lid and put the whole thing in the truck bed. The jostling of driving washes the clothes. Its an old ranchers trick.
It's fun to be me, and still legal in 9 states! Wanna see my tiny ad?
