Start with official park information, campground reservations, offline maps, and weather. Add specialized RV routing only after verifying its vehicle settings and limitations. An app is a planning aid; posted restrictions and land-manager instructions still control.
Keep official information close
The NPS app provides park information, and Recreation.gov handles many federal campground reservations. Check whether your chosen park uses a different booking system.
Download before the signal drops
Save maps, campsite confirmation, gate instructions, the route, and emergency contacts. Test that the needed information opens without a connection. Keep a paper or independent backup for critical navigation.
Check the route against your rig
Enter correct dimensions wherever a routing tool supports them, then review the route for clearance, weight, grade, and surface restrictions. A route suggested for a passenger car may be unsuitable for an RV.
