We have a 2014 Jeep Trailhawk (electric steering & automatic).
We DO NOT disconnect the battery, and we have pushbutton start, so there is no key to be left in the ignition.
Are you getting your info from the manual or a technician?
DO NOT disconnect your battery in the toad.
You need this battery to provide power to invisibrake if the breakaway switch activates (now the Coach is disconnected).
the Invisabrake has a pump which needs a fair amount of current, but only runs intermittently (when you apply your brakes). So basically the Invisabrake runs off the car battery, and the coach recharges the car battery.
What year is your jeep? Do you have LED tail lights?
