I worked for Kenworth/Paccar in Renton Wa. for a few years and they brought two truck like that in for us to check out one was the Pikes Peak challenge truck and the other was the land speed record truck. In the videos they had it melted the aircraft tires that were on it and in another it was stuck in the salt flats.
Very cool! They also did a T2000 for some TV show a few years back it was like Night rider or somthing..
