We try not to travel the interstates, so next exit wouldn't be useful to us. We do use several websites to locate campgrounds, use google maps a lot to view gas stations for layout, view the campgrounds , check mileage for approximate stopping locations and mountain directory east or west depending on where we are going. We do google searches to locate propane, grocery stores, Walmarts, or anything else we need and gas buddy to find the best prices for gas along our route. Have an atlas just in case our mobile internet isn't working or phone not working.
