Congrats on the Mountain Aire!!! There's so much fun ahead.
We use iPhones and iPads to enhance our driving and navigating experience. Here's a few apps and websites we use.
Traffic
The iPhone/ipad mapping app (preinstalled) is awesome as it shows traffic. This has saved us uncounted hours by seeing upcoming delays, allowing us to reroute around problems.
For campgrounds
rvparksreviews.com
Good Sam RV Travel Guide (app)
For fuel
Pilot/Flying J (app) we are Good Sam Life members so we get 8 cent discount off the Cash Price using the Pilot/Flying J Credit Card.
Fuel Finder (app). Will show you the closest diesel with prices
For Low Clearances
Allstays Low Clearance (app).
Weather
MyRadar (app). This gives you fast Weather Radar at your location.
Yahoo Weather (app) will auto locate you giving forecasts, radar etc.
The above is only a very small list of available apps/websites. Technology is an amazing resource to enhance your RVing adventure.
Hope this helps!!!
