The horror stories come from people who blindly trust the GPS directions, not from people who use it intelligently, and in conjunction with other tools.
With smart phone data, or downloaded maps, you can get the Google maps info along with a big "You are here" maker from the phone's own GPS receiver. GPS and digital maps are useful even if you don't ask for it for directions. And even if set to give directions, you can ignored them. It's a tool, not a boss.
Rving or not, I always try to review a days route on paper or on a computer before I start driving. State DOT sites and Google Maps can be useful in finding construction and detours. Then I enter the destination into the GPS and look at the route it chooses. Sometimes it chooses a better route, and sometimes it chooses a bad one. Having seen the route on paper, I can either see why the GPS is choosing something or scratch my head and try to figure it out.
A huge advantage of the paper map or computer screen is that I can see everything near the route. A few years ago we were headed for New England and I happened to notice that a town in New York where an old classmate moved was only about 20 miles off the Thruway. Had I not seen the town on the map, I'd have never realized we were going to be so close. Was able to meet him for a wonderful 2 hour lunch.
If I get re-routed along the way by traffic, construction or making a wrong turn, I pull into the first gas station or restaurant I can find and do a little more map reading to make sure I'm not going somewhere I don't want to go. Got detoured by a damaged bridge once, and the official detour was 14 miles. Lady at a Wendy's told us to take a county road 3 miles and there was a 4 lane state highway route that was actually a little shorter than the original route.
One of the biggest advantages of using a GPS isn't routing, but the warning that your turn is coming up and the guidance about which lane to be in. When two lanes exit, but you need to be in the left lane of the two, it's really nice to know that a mile before your exit.
