In my experience, the power steps are powered by the chassis battery. That way, if you start the engine, the steps can auto-retract even if the house battery is turned off.

Mine are connected to the house battery, but they don't have any auto-retract feature (nor did they ever). It's just a switch like a power window switch next to the entry, connected directly to the step motor. It's a simple setup, but even so most of my non-RVing friends seem to think it's Buck Rogers level technology.

If you do have the auto-retract, then the chassis battery is probably the most common connection, as I understand things. I guess most these days probably do auto-retract.
