If your Ram has Navigation
you can type in your destination while parked
If the Ram is moving, you have to use the VR button on your steering wheel, then tell the Nav where you want to go.
If you are taking a drive, going to a place where you have never been, study where you are going either on your computer & maybe print out some notes for reference, or buy map of the area.
If i am driving across country, each night i study the maps on my laptop.
I always look for Truck Routes to bypass cities

as far as the mirrors go
i just simply made it a habit to step out of the truck & press the drivers door mirror master switch & then press down on the Emergency Brake pedal with my hand & then press the master door lock button before closing the drivers door.
