You may like the thrill of using your “internal” GPS to get you where you need to go. Or, perhaps you’re old school and prefer paper road maps for longer road trips. But if you’re opting to travel by RV, an RV-specific GPS is non-negotiable. These navigation systems are specially designed to deal with the challenges of the road that you won’t face in a car—taking you away from narrow roads, low hanging branches, weight restricted bridges, low overpasses and more. Here’s what to look for in an RV GPS that will ensure you’re on the safest and most reliable route throughout your journey.
