Charge Line Kit That Allows Towed Vehicle Battery to Be Charged from Motorhome

Question:

Referred here for a device that will allow me to charge my towed car behind an RV that allows 12v from the RV to keep the car battery charged while driving. Searched but do not see it. ANy help?

The Roadmaster charge line kit part # RM-156-25 is the kit that would run a charge line from the 7-way of your RV to your towed vehicle battery. But if your motorhome didn't have this circuit active you'd also need the part # RM-156-75 and you'd be set.
