The trailer is an unpowered utility vehicle found throughout Knox Country. They can be attached to the back of all vehicles to carry an additional 100+ units of encumbrance.
Characteristics
Trailers are unpowered and thus must be towed behind another vehicle. They do not serve any other purpose besides carrying additional cargo. Be mindful that the extra weight will slow the vehicle down. It is not possible to carry players inside a trailer by any means.
The towing capability of a vehicle is governed by horsepower and not torque, so sport class vehicles are the best at towing trailers, not heavy-duty ones. Why this mechanic functions this way is unknown. It might be changed in a future update.
If the car the trailer spawns attached to is too damaged, it cannot be detached without dismantling the car wreck. Thus, it is recommended to bring metalworking supplies when trailer hunting.
Condition
A trailer can become damaged if it crashes into a zombie or any solid object. It can be repaired in the same manner as the trunk of a vehicle.

Locations
The trailer and its cover variant can be found in traffic accidents across Knox Country. 4-lane highways have the highest chance of spawning accidents, thus, it is the place that trailers are most likely to spawn.
Trivia
- When towing, trailers and advert trailers are the only vehicle types to directly attach to the rear of the vehicle.
- The trailer will always have a minimum capacity of 80, regardless of how far the condition of the trailer dips.
- While there doesn't seem to be a specific model the trailer is based off of, its design is that of a two-wheeled utility wagon.
- It is the only other vehicle that must be towed by a working vehicle other than the advert trailer.
- Damaged trailers can lose cargo. This is indicated by a thump sound.
