1989 Ford F350 with Cherry Picker

I often find commercial vehicles at salvage yards.  However, finding one with a boom lift is pretty unusual.

This '89 F350 had no markings on the doors or side panels (as far as I could tell) so I'm not entirely sure what it was originally used for.

There was only a 5 digit odometer, so I have no idea how long it was in service.  But it looks like it had a decent interior at one point.
