Expert Reply:

I do have an option for you but the Roadmaster Automatic Battery Disconnect part # RM-766 will not work on any vehicle with a diesel engine no matter the number of batteries due to power surges. Instead, you can use the Deka Lead Quick-Disconnect Battery Terminal part # DW05312 or you can use the Epicord Battery Disconnect Switch with Key part # 277-000096 and mount it inside the vehicle. I have attached some other items you will need to flat-tow a 2019 GMC Canyon below.
