Magellan wants to help out, with the RoadMate RV9145. This latest addition to the RoadMate family of GPS devices features an "extra-wide" seven-inch display, which drivers can use to locate campgrounds and navigate the open road, even in low light conditions. With the RV9145, you'll have access to the Good Sam Trailer Life RV Parks & Campground Directory, which offers information on more than 11,700 campground locations across the US and Canada, including those with WiFi and other amenities. Each route, moreover, can be tailored according to your vehicle's height, width and weight, as well as your own preferences for scenic or expedient traveling. The device also comes packed with Magellan's Smart Detour, which offers alternate routes whenever traffic gets unexpectedly thorny, and offers both 2D and 3D mapping capabilities. No word yet on when this device will hit the market, but when it does, you'll be able to grab it for $350.
