Frequently Asked Questions About Peterbilt 379 Refrigerators & Mounting Kits

Will these refrigerators fit in my Peterbilt 379, and what are the space requirements?

Our refrigerators are designed specifically for Peterbilt 379 models from 1987-2007. The most common sizes are 1.1 to 2.2 cubic feet, which fit perfectly in the sleeper compartment without interfering with your bunk space. Before ordering, measure your available space - you'll need approximately 20" width x 18" depth x 22" height for most models. The mounting kits include adjustable brackets that accommodate slight variations in cab configurations.

How difficult is the installation, and what tools will I need?

Installation typically takes 2-3 hours for someone with basic mechanical skills. You'll need a drill with metal bits, socket wrench set, wire strippers, and a multimeter. The mounting kits come with pre-drilled brackets and detailed instructions. The electrical connection requires tapping into your 12V system - most drivers connect directly to the auxiliary power panel behind the driver's seat. If you're not comfortable with electrical work, any truck shop can complete the installation in about an hour.

What's the actual power consumption, and will it drain my batteries?

These 12V DC refrigerators draw between 2.5-4.5 amps when running, cycling on and off to maintain temperature. In real-world conditions, they consume about 20-35 amp-hours per day. Your truck's standard dual battery setup can easily handle this load for 2-3 days of engine-off time. Many drivers add a dedicated deep-cycle battery or connect to their APU for extended parking. The units include low-voltage protection that shuts off at 10.4V to prevent dead batteries.

How well do these refrigerators hold up to constant vibration and temperature extremes?

The refrigerators we carry feature heavy-duty compressors specifically designed for trucking applications. They're tested to withstand continuous vibration and operate reliably in temperatures from -4?F to 110?F. The mounting kits include rubber isolation dampeners that absorb road vibration. Based on customer feedback, these units typically last 5-7 years with regular use. The compressors carry 2-year warranties, and replacement parts are readily available.

What's the difference between the various mounting kit options?

We offer three main mounting styles: floor mount, wall mount, and swing-out brackets. Floor mount kits bolt directly to the cab floor and work best for larger units. Wall mount brackets attach to the sleeper wall and save floor space but require solid mounting points. Swing-out brackets allow you to pull the fridge forward for easy access but need 6-8 inches of clearance. All kits include stainless steel hardware and fit both standard and extended sleeper configurations. Choose based on your available space and access preferences.
