Probably not, if you don’t tow multiple days without running the Jeep. I found out the hard way that several days of consecutive braking unit operation can drain a battery.
We DO often make long tows, so I just install a charge line on everything. And why not; what’s one more short piece of copper and a diode, when you’re already running all the wiring for the lights and breakaway switch?
