It looks great!

We use mainly use RV Trip Wizard. Not an app but web based. It gives mileage, clearance heights, multiple campground choices and gas stations based on your mileage and roads traveled. It will even give you estimated trip costs depending on budget numbers you set up. We love it! They also have great help for any issues you might encounter. (Operator error being my biggest issue!)

We bought from Wholesale Warranty and found it to be great! The price of the warranty has more than paid for itself. Even better...the repair companies we've had to contact have worked directly with the warranty company.
