18 Wheeler: American Pro Trucker Cheats (PlayStation 2)

Complete each of the four parking levels to unlock an additional parking level. Complete
this bonus parking level to unlock a sixth parking level.

You can earn bonus parts by completting the parking mini-game after beating your rival in
any Arcade destination race.

Complete arcade mode with all four characters. Two bonus trailers unlock in Score Attack
mode, Versus mode, and Arcade mode for all trucks except the Nippon Maru.

You can effectively draft behind trucks your size giving your truck a slight boost in
speed.

To unlock the tight, double-stacked Nippon Maru Truck, go to the title screen. Press and
hold X, then press Start. Keep holding X until you see the Mode Select screen. The Nippon
Maru truck will be available once you choose a game mode.
