The RUST Generic Vehicle Chassis is the baseline frame used to design the three primary, available chassis types in RUST. Facepunch added the modular vehicles in the Modular Vehicle Component Update on the 3rd of July, 2020.
This chassis type is not currently available in the game but remains in the files as an asset that yields an error message in the console when attempted to be spawned via the
entity.spawn vehicle.chassis command.
