Will the Battery On a 2018 Jeep JL Wrangler Drain While In Tow Using the Roadmaster BrakeMaster  


Will the RM-9160 cause a battery drain on my tow vehicle?


Expert Reply:

The Roadmaster BrakeMaster System part # RM-9160 will not drain the battery on your 2018 Jeep JL Wrangler becuase the main air cylinder is powered via vacuum. If you like, you can install the Roadmaster Battery Charge Line Kit part # RM-156-25 which will provide a charge to the vehicle's battery while in tow but this should not be needed. However, you will need a seat adapter to use the BrakeMaster on your Wrangler, the RoadMaster BrakeMaster Custom Seat Adapter part # RM-88130 for four door models or part # RM-88291 for two door models.

If you need any other parts to complete your flat-towing setup then please just let me know.
