I have no idea, but personally, even with a lot of laundry I would just do it onsite, but do it every day. I take my shower at night, so I take the laundry at the same time, drop the laundry in the washer, go to the shower, then when my shower is done, the wash is usually done, then I drop it in the dryer. I go back to the camper check email, and by that time the dryer is finished.
