I believe one of the tests is crashing into a wall that yields very little, so the tungsten dumptruck would fare poorly, exciting as it would be to drive.
The wall at left in that video is, at most, four dump trucks in volume and perhaps constructed of reinforced concrete (density ~2,500 kg/m^3)?
A single solid tungsten dump truck would have almost twice the mass of the wall. Even with a completely inelastic collision, the wall's going to shatter and move. For a 35 mph collision, I think you're right, that wall would ultimately bring the truck to a halt from friction with the ground. At higher speeds, I think the truck might make it through.
Tungsten is quite dense (19,300 kg/m^3). Such a truck would have a mass of >400 metric tons (2 x 3 x 4 m x 19 tons/m^3), or >247 Toyota Tacomas (2013 extended cab, curb weight 3560 lb --> 1618 kg).
The truck would be terrifying to drive, once you got it going. I don't know how you'd turn.
Alas, Youtube is short on tungsten dumptrucks, but this may suffice. In a demonstration, a truck uses its brakes to stop after obliterating a few cars. The truck is driven by a real person.

So around the max takeoff weight of a 747, with approximately as heavy duty a wheel setup I assume. That would be quite a truck.
