Power Steering Fluid

I have a Cummings 450 HP diesel pusher. My owners manual calls for Dextron III power steering fluid. Looking online, it would appear that this is no longer available. I found where the Dextron III ATF has been replace by Dextron VI, but nothing on the power steering fluid. Anybody an expert on this subject? Is there a good substitute?

ATF III is correct I do know napa, autozone carry it but you can also get it from and international or freightliner dealer and most autoparts stores.

dextron vi is a full synthetic fluid used in newer transmissions like the gm 4l80, I would not use this in your powering steering even though the bottle says reverse compatible with atf III it might cause leaks in the gearbox shafts.
