You would definitely want to size the donor EPS for the truck. The coupling joints alone need to be sized correctly.
Sorry, back to the failsafe discussion (mental punishment).
I don't know the answer to this question but suppose the failsafe failed and the circuit for torque assist somehow went nuts forcing the steering wheel right (meeting oncoming traffic).
You have the "shaft is solid all the way through" resistance plus the torque assist in the wrong direction, would a person still be able to steer safely?
I'm past the point of criticizing and insurance warning. I'm now just curious.
If the above happened and if it is significant, I would think using a "brake" signal via the CAN bus to deactivate the torque assist would be a needed safety feature.
