GPS scanning is a "Godsend" for trips and I'm sure you'll find it to function quite well.
Oversimplifying Range setting a little to help a new user to understand: When Range is set to 0, the scanner turns "things" on just as you enter a jurisdiction and off just as you leave. If you set the Range to 10.0 miles, "things" are turned on 10.0 miles before you enter the jurisdiction and are turned off 10.0 miles after you leave the jurisdiction.
My school of thought is that by going with a higher Range value, I may begin to hear transmissions sooner. That could give me some advance indication that an incident affecting my travel is occuring, such as a motor vehicle collision. Then I can think of a detour sooner instead of getting stuck in traffic.
