I bought an RV 6" TomTom GPS from Amazon this summer and couldn't be happier with the way it performed. Went 8400 kms with no issues this summer. I found it very easy to use and the 6" screen was a perfect fit on my F150 dash. The price was around $190 with free delivery.https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
