This may have been discussed, pardon me if it has, I just started. I'm retired and traveling with my dog. I am planning a trip from PA to AZ. I only want to drive for 5 to 7 hours between stops. Since most of my travel in the past averages 50 miles per hour along major highways, that would be around 300 miles per day. I would like to have a tool that plans my waypoints by this criteria. Is that possible?
