Note the vehicle .04 seconds in DOES have 7 roadwheels but it's also flying a Turkish flag and .21 seconds and 32 seconds in there is another one but it has six and at 1:02 were back to 7.
At 3:03 they mention adding a 7th road wheel and increasing the weight to over 60 tons with added armour
Let me know when they roll off the boat and we'll see how close this is........
