Big mutha trucks

Diplomatic immunity
Enter VICTORS in the options screen.

Hint: Save money
If you have not used a cheat and are still taking damage on your travels use this trick to save money. When you get to your destination, sell your goods but do not buy any more until after you have been to the garage. When you enter the garage, exchange trailers and the new trailer will have no damage. If you want to get your old trailer back again, just change again and the damage will be gone. Note: If you have only sustained minor damage it will probably be a better value just to repair it.

Master code
Enter CHEATINGMUTHATRUCKER or ATJCEHJMJ in the options screen. All cheats and the Evil Truck will be unlocked. If you choose to have the automatic Sat Nav, it will always take you to where you will get the best price, but you will not be able to race against the other truckers.

For the master code enter CHEATINGMUTHATRUCKER at the cheat menu.

Hint: Money $$$ Money
To get even more money after enabling the "$10 million" code, whenever you go to the bars (especially in Greenback) play the slot machines on the left. They will always pay off.

When you go to the garage to trade trailers, buy a trailer extension so you can haul more product and make more money.
