Rand McNally GPS RVND 7725-LM

I preview my road trips first with the rand/mcnally truck atlas purchased at a pilot truck stop. GPS devices chose routes that are shortest or theoretically fastest but are blind to traffic volumes in cities, etc. The trucker atlas gives me alternate routes around major suburban areas. And if a semi can drive it so can an rv. After picking a route I load my 7 inch magellan with the cities and rv parks along the chosen route. Basicall I force the GPS to follow my preferred route instead of relying on it to chose my route. I also review the planned route on the good sam trip router to confirm times and distances. For me the best part of gps is the alerts about turns and lane choices and the constant eta and distance to destination info. Also, if all else fails, I let DW review my choices on her Ipad. Advice I am famous for ignoring, haha.
