"Here's a great opportunity to earn some dough. Steal a GAI 353 Military Truck and bring it to the garage. Robbing the army is a risky business mind you. Keep an eye out for soldiers guarding the truck."
The truck is parked by the car wash at a Trago gas station in Dipton with three soldiers nearby. They won't suspect anything until you start shooting so take them out then hop in and drive it to the garage. The truck is incredibly slow and won't go over 40 mph but you have plenty of time so enjoy the short ride to the garage where you'll receive a decent payment for your troubles.
- You can obtain a Thompson M1A1 from one of the soldiers if you don't already have one or need the ammo. This weapon is needed for the Armament King achievement.
