At Mt Rainier White River campground is first come first serve. No hookup with 22 ft length limit. Your B+ no problem. I think opening date is late June, need to check date. Usually never fills up during mid week and only sometimes on week ends. There is water facets and flush toilets but no dump station. Ohanapecosh campground is on the reservation system, ,no hookups but there is a dump station. You can Mt Rainier at White River CG but not at Ohanapecosh. There are also lots of Campground on Highway 410 and 12. On Highway 410 Lodgepole campground is a great USFS Campground, all paved camp sites and very clean newer outhouse. Just outside Mt Rainier on 410 is Silver Spring and The Dalles CG, very clean, all with great HOSTS. NEED more info PM ME.
