Rucksack

Rucksacks can be used to create custom stashes, which are highly optimized for hoarding. Unlike standard containers, they can easily hold thousands of items without lagging the game out. Rucksack has a GPS tracker built in; it will warn you if any NPC steals it.
Double-click a rucksack to create a stash under your feet; its GPS tracker will appear as a mark on your map, with a hover tooltip showing the contents.
The default interface is list-based, and has filtering and sorting available. You can switch it to the classic icon-based interface if you desire.
== Location ==
The contents of most quest-related stashes are grabbed together with rucksacks, which is the main source of them. The entire game has about 500-600 rucksacks total.
== Notes ==
* You can drop a rucksack onto a vehicle and drive around with all its contents.
* Rucksacks can be used as stepstools to jump a bit higher.
* To the game engine, rucksack is a physical object with huge weight; this causes various game physics-related quirks. Sometimes they can send you flying dozens of feet into the air just by using them. When driving with a rucksack on top of a vehicle, it will collide with vegetation (unlike the vehicle itself), slide and drop onto the ground. Counterintuitively, dynamic anomalies can easily send a rucksack flying across the location.
* The icon overview allows you to carry your loot without limit.
