Getting a new Lance 1575. How to get started?

Our first psychological barrier to overcome was to learn how to backup and park the beast. We went to an empty parking lot and practiced the basics of backing and parking. I laid cones in the parking lot and practiced driving and backing around them. To communicate with each other we use a wireless phone set just like you might use in your home. We have headsets that plug-in to the handsets which gives me hands-free communication with my wife as I maneuver the truck and trailer. The wireless phone allows both of us to talk without pushing a button as required on a walkie talkie. And no cell signal is required. The phone base is powered by the inverter in the truck, or could also be powered by an inverter in the trailer. We still use the phones each time we pull into a campsite.
