If you happen to need to wash out those sleeping bags, or you're down to the last big of clothing anyone can stand to wear somewhere near Roseburg (or if you just need a place with Internet connectivity!), drive along to 4850 NE Stephens Street to Value Clean Laundromat. (It's on the west side of the road.)
I can't really believe I'm recommending a laundromat, but my daughter needed the Internet and I wanted her bedding washed, and we found this place. It has bright lights, clean tables, a kids' playroom, coin machines, an ATM, Internet–ask for it to be plugged in–and four or five sizes of washers and dryers. The ladies there are incredibly helpful, and they'll even watch your clothes for you if you need to get a bite to eat or something. It's right near Costco, so cheap eats are close.
Just watch the clock: don't arrive after 6:30 pm if you want to be able to leave while your clothes wash, and 7:30 pm is when you can start the last possible load.
