I emailed Blue-Ox yesterday (05/15/07) about the availability of the Trucenter steering control and here is their reply:
At the moment the Trucenter steering control is not available. We are
doing a redesign and extensive testing. It may be possible that it
be available late this summer. We will contact you as soon as it is
available and furnish you with a list of dealers.
