With adding some more rust, some dust and filling up the cab and roof rack the with the missing equipment and cargo, I call this vehicle done.
It is honestly great that MiniArt and other plastic model manufacturers venture into the more unique and obscure subject territory. Previously if it was not a Sherman or Tiger (with some exaggeration) you were out of luck -only very expensive kits or conversions by resin manufacturers were available. So while I would love to build the new General Motor CMP C60X by Resicast I will never be able to afford it; this model gave me something similar I actually can. We truly live in a golden age of scale modelling.
