Rucks in TrucksG 10

To unlock this achievement you simply need to gather six rucksacks and deliver them all to your base in one go with a vehicle during a Lifeline game type. Rucksacks are basically any resource (like Building Materials or Ammunition) that can be broken down into usable parts when searching in the wasteland. The easiest way to complete this achievement is to park a vehicle with six storage slots just outside the military base to store scavenged rucksacks. Once you have scavenged enough to collect all six rucksacks and placed them all in the vehicle simply drive it to the designated parking spot at the base to unlock the achievement.
