New to the site and did not look close enough at all the places to post the topic. I beleive that a 40' would fit at Douglas Falls Campground, but I would have to check to make sure. Douglas Falls Campground has power, water, sewer, phone, small pump house with limited storage, and a concrete pad. The other sites listed above do not have any amenities other than a water hand pump and outhouses. This year we will be reconstructing Sherry Creek Campground which is near the Little Pend Oreille ORV trail system. It will have many of the amenities like Douglas Falls. I will take note of all questions, take pictures, and go through the campgrounds this season and try and have a good information page for next season.
