Peterbilt 389 Glider Refrigerators & Mounting Kits

Frequently Asked Questions About Peterbilt 389 Glider Refrigerators & Mounting Kits

Will these refrigerators and mounting kits fit my Peterbilt 389 glider?

These units are designed to fit the cab and sleeper configurations found on Peterbilt 389 glider kits. Because glider builds can vary slightly depending on the sleeper size and interior layout used, we recommend checking the listed dimensions and mounting specs against your cab measurements before ordering to confirm a proper fit.

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

Most refrigerators in this category run on 12-volt DC power and are wired directly into the truck electrical system. Power draw is generally low, but if you plan to run the unit while parked for extended periods without the engine running, it's a good idea to monitor battery health or use it in conjunction with an APU or auxiliary battery setup to avoid unexpected drain.

Do I need the mounting kit, or can I install the refrigerator on its own?

The mounting kit is built to securely anchor the refrigerator in place inside the cab, which helps prevent shifting or damage while driving. While some drivers attempt custom mounting solutions, using the matched mounting kit is the more reliable option since it's designed specifically for the dimensions and weight of the corresponding refrigerator unit.

How much interior space does a typical unit take up?

Refrigerator sizes vary by model, so available cab and sleeper space should be measured before purchasing. Check the product listing for exact height, width, and depth so you can confirm it will fit in your intended mounting location without interfering with other cab components or storage.

What tools or skills are needed to install the refrigerator and mounting kit?

Installation typically involves securing the mounting brackets to an existing structure in the cab and connecting the refrigerator to a 12-volt power source. Basic hand tools and some familiarity with 12V electrical connections are usually sufficient, but if you're not comfortable with wiring or drilling into cab surfaces, having a qualified installer handle the job is a safe option to ensure everything is mounted securely and wired correctly.
