The seat and steering wheel on most lift trucks are offset left of center, correct?
The control levers are mounted on the right, leaving the steering wheel on the left, correct?
This offset allows for operator to rotate to the right when backing and keep body parts inside overhead guard supports, correct?
This is not "Rocket science", Let us use common sense.
It would seem to me that the "left" hand is going to be the likely choice to turn the wheel.
It's obvious that in certain situations, using the right hand on the wheel will be necessary, but for normal average operation, left on wheel and right on controls except when backing.
To me it's no more difficult to turn the wheel CW or CCW with the left hand especially if a wheel "****" is installed.
