Like I said I thought I thoroughly checked the route, but missed the tight curves/almost switchbacks. And again google maps is good and I trust it when out west, but in the east with the tight roads everywhere it’s no good. And you can only pre check a 400 mile route so much. At 400 miles something will get past you. The GPS is a tool to go along with the knowledge on how to use it. I haven’t gotten stuck because of this thinking. But I prefer to skip backroads in the MH unless I’m well aware of what to expect!
If you are doing a 400mile day, it's probably mostly freeways and major roads except at the beginning and end. Not too many tight switchbacks on the freeway system, so just focus on the non-freeway part.
Never had an issue quickly finding tight areas with a quick pre-check.
