We are looking to make a 'practice' run this Spring, making a cross country trip for 6-8 weeks. It could very easily lead to a full-time period, depending on how it (and some work items) works out. ...
we just bite the bullet and do the laundry every 10 days or so. we find a laundrymat in a big parking lot if we can and spend the night there. or if we stop over at a nice campground with a laundry room, we do it there. It takes about half a day to do three or four loads and get them dried and folded and re packed.
