My latest GPS unit is the GARMIN RV 785 with traffic. The unit includes a dash cam for front view use, lane departure, front end collision warning, voice command to access items in the unit and will pare with your smart phone for hands free calling. You can specify the parameters of your trailer such as height length and weight. This has all you need for pulling a large 5er.
The unit has a magnetic suction cup mount that the power cord is connected to so, all you need to do is give a slight pull to remove the GPS when not in use. This way the unit will not have power issue in the future with the power connection.
I have used other such as a Rand McNally but this Garmin is far superior to the Rand McNallys I have used in the past.
