My 1986 has the Saginaw GM tilt steering column. Functionality; tilt, turn signals, horn, steering lock, ignition key. Repair Manual.

I looked at replacement steering wheels that had additional functionality like the IMMI VS4 series.

It would be a great solution if my coach was fully J1939 CANbus compliant, but unfortunately, only my engine and transmission are.

I'll probably end up getting a steering column that has tilt, telescoping, windshield wiper, washer, head light, and cruise control on the column with a steering wheel that gives me control of the radio, and hands-free Bluetooth. With programable CANbus controllers, this shouldn't be an issue mixing vehicle-specific and J1939 protocols.
