Does anyone have an explanation why this is not the case?

Welcome... from another Washingtonian! It doesn't make much sense to me either. When you park the rv and turn off the engine, the radio/screen system should turn off. Then, turn on when back in the rig starting the engine. I'll bet a person could re-wire to a hot ignition "ON" power source Pretty easily.
