How can you make an old semi with power steering turn faster?

I guess by process of elimination if that is indeed the problem then the solution will require either a custom install of a gear set for it or something else able to create a bettter turning situation.

I eyeballed that short truck picture and it's really short. I was getting ready to consider if you are trying to back a 20 foot Shipping box or something like that. (I hate backing those. I cannot "Stay Under" one of those to save my life.

And then the memories of similar beasts came up from long ago. In those days with them all I had was either a 30 foot milk trailer or a 40 foot box with one similar rig in particular.
