Question about 12V charging on Jeep JL while flat towing
I've flat towed a Jeep a TJ and a JK behind the MH with zero problems. Now I'm getting ready to flat tow my 2018 JL Jeep Rubicon. It is a whole new beast as far as the electrical system goes with it infamous stop/start system and two batteries.
I'm using the Cooltech wiring harness and a Brake Buddy II braking system. I'll power the Brake Buddy from the 12V outlet in the back cargo area since it is live all the time.
So, here is the question. Do I need an axillary charging system to keep the battery up for the Brake Buddy on the JL? Cooltech is pushing their charger. Is it a real need or just revenue enhancement? On the TJ and JK I never worried about the Brake Buddy draining the battery on a one day tow. If I towed for two or more days, I would just let the engine idle for ten minutes or so first thing in the morning to top off the battery.
