Came across a great article - "Must Have RV Apps to Make Your Life on the Road Much Simpler."
The entire article is available in the provided link, but here are some of the Apps mentioned:
1) Walmart Parking App - Tells you where every Walmart is located and whether you’re allowed to park there overnight.
2) Truck Stop App - Helps you find truck stops wherever you are, so you won’t struggle to find your closest stop anymore.
3) RV Dump App - Gives you all the details about where to get repairs, fuel or stay overnight.
Others (free): Google Navigation/Maps, Passport America, Gas Buddy, TV Antenna Helper, Weather Bug, Key Ring
Others (paid): Camp and RV Campgrounds Plus, Satellite Finder
