What's the recommended connection point in a motorhome for 12 VDC to power an HF rig that draws about 20 amps during TX?

Since I won't be operating while in motion, my first thought is a direct connection to the house batteries or the battery disconnect switch. But then I begin to wonder if the connection should be at the converter 12 VDC house output, so as not to upset the multi-stage charging function, which depends on battery voltage.

Will a direct connect to the battery confuse the converter's charging function?

Would a connection to the converter be preferred?

What are you using?
