Overview
This proposal combines comfortable supply nights with simple campgrounds and free overnight stays. After two to three self-sufficient nights at the latest, a place with fresh water and disposal is deliberately followed again. Where Boondocking with a large Fifth Wheel does not make sense, the plan remains with an official campground.
Recommended basic rhythm
Camping with service → 1–2 nights Dry Camping or Boondocking → Camping with water and dump station. In case of heat, cold or high consumption supply earlier.
Accommodation plan along the route
Type | Stage / Area | Recommendation & Supply
Camping + service | Coeur d-Alene | Coeur dAlene RV Resort or Blackwell Island RV Park. Full hook-up for water, dump, laundry and shopping use.
Boondocking | Kaniksu National Forest | Dispersed camping on according to MVUM permitted routes around Lake Pend Oreille. No infrastructure; forest roads and turning point first check.
State Park Camp | Farragut State Park | Good intermediate station with large RV sites. Water and dump are seasonal; choose suitable connection type when booking.
Camping + service | Wallace / Silver Valley | Wallace RV Park or Blue Anchor RV Park. Supply stop in front of the long mountain and forest stages.
Dry Camping | Stanley / Redfish Lake | Redfish Lake, Stanley Lake or any other Sawtooth Campground. Mostly no connections; fill tank in Stanley and check vehicle length.
Boondocking | Sawtooth National Forest | Only existing, allowed places – e.g. in designated dispersed areas of the Wood River Valley. No supply; not every access road fits for a Fifth Wheel.
National Monument Camp | Craters of the Moon | Lava Flow Campground is Dry Camping. Water is available seasonally, a dump station is missing; previously supply in Arco.
Camping + service | Twin Falls | Twin Falls/Jerome KOA or Oregon Trail Campground. Full hook-up and great shopping in front of City of Rocks.
Dry Camping | Milner Historic Recreation Area | Cheap BLM-Campground with individual large sites, but without water, electricity or dump. Use western entrance due to low passage.
Camping + service | Boise | Riverside RV Park or Boise/Meridian KOA. Complete service stop at the end of the Idaho stage.
Important for a big Fifth Wheel
Always check Boondocking access roads first without trailer. Only use public, legally accessible and already used areas. Before each journey current blockings, fire regulations, motor vehicle use maps, ground conditions, maximum vehicle length and turning area on the official pages of BLM, US Forest Service, National Park Service, State Parks and Recreation.gov control. Taps only for filling tanks if this is expressly allowed.
Search status: August 2026. Opening hours, fees, reservations, water and dump stations can change seasonal or short term.
