Pressure pro for the coach and the toad.
The DW has a TomTom that I hate. I use the Co-Pilot RV app on a tablet along with Waze for traffic. Whatever GPS you decide on, make sure it has a mode that takes into account the height and weight of your rig.
Always pick "fastest route" vs. "shortest route".
