Looks like the one in your avtar, at the track. Has a front runner, a decent size rear tire, NX sticker in the windshield, perhaps an electric fuel pump in the rear.. Looks like it could be a racer to me.. Not sure why it got moved other than you made no mention of it being a race truck. Only reason I could think of..
