Peterbilt 589 Refrigerators & Mounting Kits

Frequently Asked Questions About Peterbilt 589 Refrigerators & Mounting Kits

Will a 12V refrigerator for the Peterbilt 589 drain my truck's battery while parked?

Most 12V truck refrigerators are designed to run efficiently off a truck's battery system, but actual power draw depends on the compressor size, ambient temperature, and how often the unit cycles on and off. If you plan to run the fridge for extended periods without the engine running, it's a good idea to pair it with an auxiliary battery, battery monitor, or APU to avoid draining your starting battery. Checking the wattage and amp draw listed on the specific unit you're considering will help you plan accordingly.

Does the mounting kit fit the factory sleeper cabinet in the Peterbilt 589, or will I need to modify anything?

Mounting kits in this category are built to work with the Peterbilt 589's sleeper compartment layout, but fit can vary slightly depending on the refrigerator model and cabinet configuration you have. Reviewing the listed compatibility details for both the fridge and the mounting kit before ordering is the best way to confirm a proper fit. In some cases, minor adjustments like bracket positioning may be needed to get a secure, flush installation.

What size refrigerator will fit in the space available in my 589?

Refrigerator capacity is one of the most common concerns, since sleeper storage space is limited. Product listings typically include exterior dimensions along with capacity (measured in quarts or liters), so measuring your available cabinet space before purchasing is recommended. Going a size up or down from your factory unit can sometimes require a different mounting kit, so it's worth double-checking dimensions against the kit you're pairing it with.

Can I install the refrigerator and mounting kit myself, or does it require professional installation?

Many drivers and owner-operators install these units themselves, since the mounting kits are designed to simplify the process with pre-drilled brackets or slide-in tracks. Basic tools and some familiarity with 12V electrical connections are usually all that's needed. If your installation involves running new wiring or modifying cabinetry, having a technician handle it can help ensure everything is secure and wired safely.

How do I keep the refrigerator secure while the truck is in motion?

This is where the mounting kit becomes essential -- it's designed to hold the refrigerator firmly in place during driving, preventing shifting, vibration damage, or the unit coming loose over rough roads. Making sure the kit is rated for your specific refrigerator's weight and dimensions, and that all mounting hardware is properly tightened, will help keep the unit stable and functioning correctly over the long haul.
