We have found the best weather app for RV travel. It takes the National Weather Service's weather forecast, showing RVers the weather along their route at the time they reach each point. It allows comparison of different routes, creating stops, interactively changing departure times, and other features that help RVers plan trips around the weather. The Drive Weather app is all about decision-making in regard to the weather. Like a pilot before taking off in an airplane and checking the expected weather en route, the app takes just a few seconds to get “briefed” on the safest route and safest time to leave.
