[Fulltiming]

I have heard that the Rand McNally 7720 is brighter. My biggest complaint so far with the Dezl is that a number of roads that show up in the Rand McNally Motor Carrier Atlas as truck routes (don't know if the 7720 recognizes them), show up on the Dezl as "Truck Accessibility Unknown". Other than that, I am pleased. I drove to Georgetown yesterday and both my Android Google Navigation system and the regular Garmin showed taking some residential streets to get to the destination which was on the southbound service road (I was traveling North). The Dezl had me go to the next exit and come back down the service road which would have been a far better route in the RV.
