9 free RV apps actually worth downloading.
There are dozens of RV apps and most of them are bad. Here are the nine that earn space on the home screen, all free at the level you actually need, all road-tested, no affiliate fluff.
Camphost
Yes, this is our list and yes, we put ourselves on it. Camphost is a free AI co-pilot built specifically for RV troubleshooting and trip planning. Ask in plain English ("my fridge is warm and clicking"), get walked through the diagnosis one step at a time. No signup, no paywall, no ads.
Best for: anyone who'd rather ask a question than search a forum.
iOverlander
The community-built campsite database that overlanders and full-timers actually use. iOverlander pins free dispersed sites, BLM camping, paid campgrounds, dump stations, water fills, propane, and even hardware stores. Crowd-verified with real photos and dates.
Best for: boondocking, finding free sites, anything off-pavement.
Campendium
Crowdsourced reviews of campgrounds and free camping areas, with verified cell signal data per site. The signal data is the killer feature, you can pre-screen for sites that have AT&T or Verizon before you commit. Free tier covers most of what you need.
Best for: remote workers and full-timers who need a signal.
RV Trip Wizard
Not free forever, but the free trial is generous and the paid version is worth it for big trips. RV Trip Wizard plans routes that account for your rig's height, weight, and fuel range, flags low bridges and grade limits, and finds campgrounds along the way.
Best for: serious trip planning before a long drive.
GasBuddy
The classic fuel price app, still the best. Crowdsourced fuel prices for every gas station in North America, filtered by diesel if you need it, with route planning to find the cheapest fuel along your way. Saves real money on long drives.
Best for: every RV class, especially diesels.
Sanidumps
The largest crowd-sourced database of dump stations in North America. Filter by free, paid, public, private, by state, by amenities. The website is ugly, the database is unmatched. Bookmark it.
Best for: knowing where you can dump before you need to.
Windy
The weather app for people who actually need to know what's coming. Windy shows wind speed, gusts, precipitation, and storm tracks on a beautiful interactive map. Critical for awning decisions, towing safety, and avoiding pop-up summer storms.
Best for: anyone with an awning or who tows in wind.
Google Maps (offline mode)
You already have it. The trick most RVers don't use: download the offline map for your destination region before you go. Offline Google Maps still does turn-by-turn navigation when you have no signal, which happens constantly in good camping country.
Best for: free, simple, already on your phone.
Coverage? by NPSignal
Look up actual cell tower coverage maps for AT&T, Verizon, T-Mobile, and US Cellular for any location. Better than the carrier-published maps because it shows real coverage based on tower locations, not marketing maps. Pair with Campendium for full pre-trip signal planning.
Best for: remote workers and anyone who needs to be reachable.
