looking through the observers fighting directory it is very similar to the 5-6 ton Utility line (FWD HST-COE) but these were 4X4 and also had a lower bonnet line then what is showing in the Pic. Otherwise could it be a GMC-AFX 4X2 COE with the searchlight type double cab fitted?
Hmmm May have to give this more thought But I do not think it is a Mack or Federal but a 4 to 6 ton rating is entirely possible.
