The BCC may or may not have the Reverse charge function (House to Chassis) to find out GOOGLE the make, model number manual and read the PDF file (OR dig it out of your owner's manual pack)
By the way I strongly suggest using Google to find a PDF of the owner's manual for most things in/on your RV including the TV. Fridge, Microwave, Sat Receiver. Inverters or converters. THe BCC and so on. Slide outs as well.
Store the PDF on your hard drive for quicker access in the file path

I also have /Manuals / Ham Radio on my HD just so you know
