It's a 14 day trial, after which I expect you pay.
What I like - you can quickly reposition the viewing area by moving the outlined box on the map of the country. Much easier than zooming out and dragging. The user interface is more traditional .NET stuff rather than a web based interface, however either is fine depending on what you're use to.
What I don't like - needs a separate GPS on COM port. My laptop doesn't even have a COM port! I tried plugging in TomTom to a USB port and configuring that, but I could find a place to use a USB port instead of a COM port. Also the database isn't as comprehensive as Google Maps. I plugged in Aces High RV Park as a destination and hit Find and it didn't come up with it. However I added Aces High RV Park as the destination in the route planner and it found it. Then I added my next stop - Timberlane RV Park, Clarksboro NJ - and it did not find this place. If you need to go to Google to get an address, I expect any reasonable person would just stay there and use maps. Also, no traffic.
In general, I think I get better info from Waze or Copilot RV.
