the Cameo is a 55-early 58 standard 3100 1/2T stepside with the fibreglas bits added and the deluxe trim options, nothing about the actual truck is any different than what could be found on the other madels .... notice in the assembly manual [applies to all Task Force trucks, 55 to 59] that each page shows the series/models that it applies to, and there are only a few pages that are for model 3124 only
