I have used it in the past. It works great for point A to point B, but, I had a very bad experience on a non RV friendly road it sent me on. To be fair, I should have re-routed myself when I saw the "not reccomended for vehicles over 40' in length" (I'm less) but, I didn't want to take the time to re-route. So now I always check a route against the truckers atlas. I just purchased RV Wizard (I will post a review another time) and found that it also had me going on a route that was not recommended per my truckers atlas. So, I would say, buy a truckers atlas, and whatever source you use, check the route against that
