We all know that an actual working car will be added sometime in the future to Rust, how about a rundown open back pick up truck concept. You would be able to store items in the back bed of the truck, once items have been placed in the truck’s inventory in-game the truck’s bed would appear full (items crates, etc). Thus when a truck passes by people (or Bandits most likely) would be able to tell if the truck is actually worth stopping and raiding. Also this concept could allow your mates to hop in the bed of the truck and shoot or just ride along.
Note my pro photoshop skills ;D
