Here is link to web page describing the history of the Suburban Carrier. GM made the ~300 Suburban Carriers with the idea that they would send one to every dealer in the US. The box and everything on it is identical to the Cameo Carrier box. This web page also describes that they made a small window Suburban Carrier.
