Old Freightliner Expertise Needed...

I never have driven an air power steering system. I know the old deuces had an Air-O-Matic upgrade that was probably the same type of system. How much does it drain off the pressure? Do you need a pretty stout compressor for those?

Lol, I do like the stick and throttle lock ideas though. Had an old C60 with a gasser that had a throttle lock on it. Worked great picking up hay with a bungee cord to hold the steering wheel straight. Right up until you hit that woodchuck hole, ha ha ha.
