Here's another 6mm vehicle from Brigade Models – in this case, the variant with the "office body." link
I don't think the prolific javelin98 has statted this one before, though he did do the "regular" truck: link
My version is very close, but I've gone for Low Mobility as I don't see this truck doing well off-road, I've given it a little armor (imagining it to be in military service), and I've gone for the cheaper power source.
