The dreaded Bluebird 1998-2003 sove versions of this year range were manufactured with the window frames overlapping the conduit panel cover that require you to remove all the windows on one side of the bus to get a camera to the rear of the bus. Total install time for these buses was 10 + hours each. We located a source for PVC cable raceway that permitted install of rear camera in about 15 minutes. Call us if you run into this and we will direct you to the supplier of the raceway.
