November 24, 2025
A refrigerated truck is a significant investment. When buying one, you’ll want to ensure you’re getting a reliable vehicle that will keep your cargo safe and your business running smoothly. Before you commit to a purchase, it’s essential to know what to look for when buying a reefer trailer and conduct a thorough inspection.
This article lists 10 things to inspect before buying a used refrigerated truck, helping you make a smart and informed decision. Whether you’re looking at used refrigerated straight trucks for sale in Ohio or elsewhere, these tips will help you assess the quality and condition of any reefer truck you’re considering.
-
The Refrigeration Unit Itself
This is the heart of the truck, and it needs to be in excellent condition.
- Hours of operation. Check the number of hours the refrigeration unit has been operated. The higher the hours, the more prone the unit will be to developing problems.
- Temperature control. Test the unit to make sure it can reach and maintain the required temperatures. It’s a good idea to let it run for a while to see if there are any fluctuations.
- Inspect all hoses, seals, and connections for any signs of fluid or air leaks. A UV coolant leak detector can be a helpful tool for spotting leaks that are not visible to the naked eye.
-
The Insulated Box
The condition of the insulated box is just as important as the refrigeration unit.
- Interior and exterior damage. Carefully inspect the interior and exterior walls, floor, and roof for cracks, holes, or other signs of damage. Any breaches in the insulation can compromise the truck’s ability to maintain a consistent temperature.
- Door seals. Check the door seals for any signs of wear, tearing, or gaps. A good seal is crucial for keeping the cold air in and the warm air out.
- If there are any leaks in the box, the insulation can absorb water over time, adding significant weight to the trailer and reducing your payload capacity.
-
The Engine and Transmission
While the refrigeration components are vital, don’t forget that it’s also a truck.
- Engine inspection. When the engine is cool, check for any oil splatters or leaks. Look for loose connections or worn belts in the engine bay.
- Transmission health. During a test drive, pay attention to how the transmission shifts. Any clunking, grinding, or hesitation could indicate a serious problem.
- Service records. Request the truck’s service records to determine if it has been regularly maintained, including oil changes.
-
Tires and Brakes
These are critical safety components that shouldn’t be overlooked.
- Tire condition. Inspect the tires for wear and tear. Uneven wear patterns can indicate issues with alignment or suspension.
- Brake performance. During your test drive, test the brakes at various speeds to ensure they are responsive and provide a firm pedal feel.
-
The Frame and Suspension
A solid foundation is essential for a heavy-duty vehicle.
- Frame inspection. Inspect the frame for cracks, bends, or signs of rust. Frame damage can be expensive to repair and can lead to other problems.
- Suspension check. A well-maintained suspension ensures a smooth ride and helps to protect your cargo. Visually inspect the suspension components and “bounce” the corners of the truck to check for excessive movement.
-
Electrical System and Lights
A faulty electrical system can be a major headache.
- Turn on all the lights, including headlights, taillights, brake lights, and turn signals, to ensure they are functioning correctly.
- Electrical connections. Check the electrical connections for any signs of corrosion or damage.
-
Cab Interior
While not as critical as the mechanical components, the cab’s condition can reveal a great deal about how the truck was treated.
- Seats and upholstery. Check the seats for rips, tears, or excessive wear.
- Controls and gauges. Ensure all controls and gauges are functioning properly.
-
Vehicle History and Maintenance Records
A comprehensive vehicle history is invaluable when considering a used vehicle, such as a refrigerated truck. When you’re learning how to inspect a used reefer trailer, this step is crucial.
- Accident history. A vehicle history report can tell you if the truck has been in any accidents.
- Maintenance records. As mentioned above, service records are a reliable indicator of how well the truck has been maintained.
-
Handling
There’s no substitute for getting behind the wheel. As far as what to look for when buying a reefer trailer, a test drive is non-negotiable.
- On the road. Take the truck for a test drive on various roads, including highways and city streets, to assess its handling.
- Listen for noises. Pay attention to any unusual noises, such as squealing, grinding, or rattling.
-
Overall Condition as Assessed by a Professional
Even if you’re a seasoned driver, it’s always a good idea to have a professional mechanic inspect the truck before you buy. While your understanding of how to inspect a used reefer trailer is helpful, their perspective on the condition of a refrigerated truck is also essential. You get:
- An expert opinion. A professional can spot potential problems that you might miss.
- Peace of mind. A professional inspection can give you the peace of mind that comes with knowing you’re making a sound investment.
