Peterbilt 375/377 Refrigerators & Mounting Kits

Frequently Asked Questions About Peterbilt 375/377 Refrigerators & Mounting Kits

Will a refrigerator mounting kit fit my Peterbilt 375 or 377 without modification?

Mounting kits in this category are designed to match the factory mounting points and cab layout of the Peterbilt 375 and 377 models. That said, it's important to confirm the exact year and cab configuration of your truck before ordering, since interior layouts can vary slightly across production years. If you're unsure, reach out to our team with your VIN or truck details and we can help confirm fit.

What size refrigerator will fit in my Peterbilt sleeper?

Refrigerator size is limited by the available space in your sleeper cab, typically behind the seat or in a designated cabinet area. Most units offered for these trucks are compact 12-volt refrigerators sized specifically to fit factory or aftermarket mounting brackets without blocking walkways or storage access. Check the listed dimensions of both the refrigerator and the mounting kit against your available space before purchasing.

Do these refrigerators run off the truck's battery, and will they drain it overnight?

Most refrigerators sold in this category are 12-volt units designed to run off your truck's battery system. Power draw varies by model, so it's worth checking the amp draw listed on the product page against your truck's battery capacity and any idle-reduction or auxiliary power system you have installed. Many drivers pair these units with a battery monitor or auxiliary power unit to avoid running down their starting battery during extended parking.

Can I install the mounting kit and refrigerator myself, or do I need a professional?

Many of our customers install these kits themselves using basic hand tools, since the brackets are designed to bolt into existing mounting points. However, if your installation requires running new wiring or modifying interior panels, some drivers prefer to have a shop handle that portion of the job. Installation instructions are included with most kits, and our support team is available if you have questions before or during installation.

What's the difference between a refrigerator and a mounting kit, and do I need to buy both?

The refrigerator is the actual cooling unit, while the mounting kit is the bracket or frame system that secures it in place inside your cab. If you already have a compatible refrigerator and just need a way to mount it securely, you can purchase the mounting kit separately. If you're starting from scratch, we recommend checking whether the refrigerator you're interested in is sold with a matching kit or needs to be paired with one separately to ensure proper fit.
