Okay, that explains a lot.
In Belgium a truck is in fact a big rig, like the volvo's, scania's, renaults and other brands. From time to time we see a rare Peterbilt or Kenworth, but mostly these are used for publicity or shows.
But on the Dutch Jeepforum, we have this saying: "Your SUV is not a Jeep, my Jeep is not a SUV"...
