We use a combination: for trip planning we use RV Trip Wizard, RVTW. It's about $30 a year. It routes you on a path that takes your RV size into account and has a very full set of Points of Interest: gas stations, various retail outlets like Walmarts, dump stations and many more: and various campgrounds that you can filter by membership like Passport America or Good Sams and various ratings. It has a app RV Life for your android phone to go with it. This is being actively developed and the guy doing it listens to users. He just today updated the Range Circles feature to show actual road mileage in response to requests. This feature draws a couple of circles on the map showing you desired daily driving range. I have it set for 250 and 300 miles for me.
RVTW does show free campsites but apps like freecampgrounds.net show many more if you are going to boondock.
But you should always have a paper map on hand to verify any of these software programs. RVTW has been fairly reliable in not doing strange routing so far.
In the Truck we us an old 2015 copy of Streets and Trips for the actual navigation. No connection needed to run it but it will send you on strange routes if you are alert.
