Peterbilt 357/378 Refrigerators & Mounting Kits

Frequently Asked Questions About Peterbilt 357/378 Refrigerators & Mounting Kits

Will this refrigerator fit my Peterbilt 357 or 378 without modification?

Most refrigerators in this category are designed to work with the factory mounting locations found in Peterbilt 357 and 378 model trucks, but sleeper configuration, cab size, and model year can affect fit. Always check the listed dimensions and compatible model years against your truck before ordering, and reach out to our team if you are unsure whether a specific unit will fit your cab layout.

Do I need a separate mounting kit, or does the refrigerator come with one?

This varies by product. Some refrigerators are sold as a complete package with a mounting kit or bracket included, while others require the mounting hardware to be purchased separately. Check the product description carefully, and if a mounting kit is not included, look for a compatible kit listed in this same category.

What power source do these refrigerators use, and will they drain my battery?

Most 12-volt truck refrigerators are designed to run off your truck's electrical system and are built with low power draw in mind for overnight use. That said, running a refrigerator for extended periods while parked can draw down your battery, so many drivers pair these units with an auxiliary power source, battery monitor, or idle management system to avoid unexpected battery drain.

How is the refrigerator secured in the cab, and will it move around while driving?

Mounting kits are designed to anchor the refrigerator to the cab or sleeper structure so it stays in place during normal driving conditions, including turns and rough roads. Proper installation following the kit's mounting points is important for keeping the unit stable, so make sure all provided brackets and hardware are fully tightened during setup.

What is the typical installation process, and can I install it myself?

Installation generally involves securing the mounting bracket or kit to an existing structural point in the cab, then setting the refrigerator into place and connecting it to power. Many drivers install these units themselves with basic hand tools, though the exact steps depend on the specific refrigerator and mounting kit you purchase. Refer to the manufacturer's instructions included with your unit, and contact our support team if you have questions before you start.
