Midwest Reefer — Reefer Unit Sound Mod
A reefer unit sound for refrigerated trailers in American Truck Simulator. Created by Midwest Reefer Transport of Lincoln, Nebraska, this mod is for anyone hauling chilled or frozen cargo who wants to hear the reefer running.
How it sounds
– Coupling: When you couple a reefer, the landing gear lifts, a short beep sounds, and the reefer unit starts.
– While running: The unit produces a steady hum while parked and while driving, both inside and outside the cab.
– Uncoupling: When you uncouple the trailer, the unit shuts down and the hum stops.
– Loading a save: If you load a game with a reefer already attached, the hum starts right away. You do not need to couple the trailer again.
– Traffic: Reefer trailers in traffic also hum, quietly and only when nearby.
Supported trailers
SCS Box reefer trailers in 28-, 45-, and 53-foot lengths, including doubles, from both the Freight Market and your owned trailers. No DLC is required.
How to enable
– Open the Mod Manager in the game and enable “Midwest Reefer — Reefer Unit Sound.”
– Apply the changes, load your profile, and couple a reefer.
Volume
Adjust the reefer volume in Options → Audio using the “Trailer noise” slider. Move it left to lower the volume or right to raise it. The hum is quieter inside the cab than outside.
Notes
– To keep the hum playing while driving, the mod plays it together with the trailer tire sound. As a result, it replaces the trailer tire sound; the truck tire sound is unchanged.
– Owned SCS Box trailers use the same chassis in the game for box, insulated, and reefer bodies. On an owned trailer, the reefer will run with any body.
– After starting the game, the hum plays with any trailer until you have coupled or uncoupled a reefer at least once. The first reefer coupling or uncoupling corrects this behavior.
– Outside the truck, the hum is barely audible when the camera is pointed directly at the front of the truck. This is how the game muffles trailer sounds.
– Suitable for single-player and Convoy. Other players do not need to have the mod.
– Game version: 1.61.
