The Bus Side Trunk is a storage compartment built into the side of the long buses found on many of the maps. One important note: this container must be breached to access its contents, so make sure you are not in a fight or in danger of being jumped when choosing to loot one. Bus Side Trunks do not spawn on all of the buses, just some. The loot pool leans mechanical and electrical. Rusted Tools are a confirmed drop, and the broader pool includes mechanical and electrical items alongside miscellaneous items. The exact pulls will vary, but the theme is consistent. This is a container geared toward players who need industrial & electrical crafting materials rather than combat gear or valuables. Is it worth breaching? That depends on your loadout and current crafting needs. Breaching puts you at high vulerability and makes tons of noise, so it's worth asking whether the expected loot justifies it before committing. If you're on a focused industrial materials run through Power Generation Complex, the Bus Side Trunk is a reasonable target to work into your route. If you'refocused on other loot priorities, do not want to risk dying, or short on time it's an easy skip. Worth flagging on your map if mechanical and electrical components are of essence.
