REFRIGERATORS

Refrigerators For Peterbilt Trucks

A cab refrigerator is one of the most practical upgrades for a long-haul Peterbilt sleeper — it lets drivers store fresh food and cold drinks without relying on truck stop meals every day, cutting costs and supporting better nutrition on the road. Modern 12V and 24V compressor-based truck refrigerators maintain true refrigeration temperatures without the limitations of thermoelectric coolers, and many include a freezer compartment. We carry 12V truck refrigerators and coolers sized for Peterbilt sleeper cab installations.

Frequently asked questions about refrigerators

Will a 12V refrigerator drain my Peterbilt's batteries overnight?

A quality compressor-based 12V truck refrigerator draws 3–5 amps on average, which over a 10-hour rest period adds up to 30–50 amp-hours of battery consumption. Most Peterbilt sleepers run dual Group 31 batteries with 200+ amp-hours of capacity, which is generally adequate for overnight refrigerator use if the batteries are in good condition. Drivers who also run CPAP machines, bunk heaters, and other accessories should audit their total overnight electrical load and consider an auxiliary battery or APU if the combined draw approaches battery capacity.

What size refrigerator fits in a Peterbilt sleeper?

Most Peterbilt sleeper cabs accommodate refrigerators in the 20–45 liter range, which fits comfortably in the overhead cabinet, bunk-side cabinet, or floor space behind the seats depending on the sleeper configuration. Measure your available space carefully — refrigerator dimensions vary significantly between models, and clearance for the unit door to open fully is as important as the body dimensions. Many truck refrigerator brands publish fitment dimensions specifically for common Peterbilt sleeper configurations.

What's the difference between a compressor refrigerator and a thermoelectric cooler for a truck?

A compressor-based refrigerator works like a household unit — it actively pumps heat out of the interior and can maintain temperatures down to freezing or below regardless of ambient temperature. A thermoelectric (Peltier) cooler uses an electric current to create a temperature differential and can typically only cool 40°F below ambient — meaning on a 90°F summer day it can only reach about 50°F inside, far above safe food storage temperature. For drivers storing perishable food, a compressor unit is the correct choice despite its higher price.
