I do my laundry like John Steinbeck did in his non-fiction book; "Travels With Charlie" in his truck camper. I fill the 3.5 Gal. bucket with clothes needing washed, add some laundry detergent, fill with water in the floor of the coach shower, stir it up and let it soak for hours and even driving on your trip for hours too, before rinsing with water and hanging the clothes on white plastic hangers, first in the shower stall to drip first, then around the interior where they can finish air-drying.
