When I planned my 5k mile Yellowstone trip I used RV Trip wizard, when I did my 2,100 mile Acadia and NYC trip I used Furkot. To me if I was doing another big trip RV Trip Wizard is the no brainier, especially now that you can directly import the trip into the RV specific GPS in the RV Life app for a few bucks for a month pass, no question the route I'd go. It makes it so easy to see reviews, filter by amenities, price, etc and see the distance between stops and about where you'll need gas and check for stations ahead of time.
