It is a movie prop made for the G.I. Joe movies, known as the Devinator MRAP. It has been used in quite a few movies and TV shows.
It appears to be based on a standard 6x6 M800 series 5-ton truck with "Bigfoot" tires. Compare the placement of the fuel tank and air intake on the left side, the battery and storage boxes below the passenger door, along with the suspension and fender supports, etc., etc...
