Hmm... that's a good point. I don't have a Sleep Number in the RV but we do have one at home. Once our mattress is filled with air to the desired firmness it remains at that number for a very long period of time. I think you could unplug the unit and it would remain at that firmness until you wanted to change it. So I'm guessing that periods of dry camping would not pose a significant problem.
You could also use an appropriately sized inverter to take power from your batteries and convert it to 120 AC to run the Sleep Number pump/control. When the pump/control is plugged in it probably uses a small amount of power to keep its brain active but it's not as if the pump has to run regularly to maintain the pressure.
The above is speculation on my part based on my home experience. I'm sure somebody with direct experience will chime in here.
