Buying a semi truck is more than a business transaction. It’s a commitment that can shape your career, finances and daily life, so choosing the right one is critical. A thorough inspection can help you get the best value for your money. Here are four things to check before sealing the deal. 

1. Trucking Type

A semi truck with a heavy-duty, high-horsepower engine is inefficient for light, local deliveries. Before anything else, ensure you have the right truck type for the job. Answer these questions to narrow down your options: 

  • Will you be hauling heavy or light loads? 
  • Are you driving on highways, city roads, or mountainous terrain?
  • What kinds of cargo are you transporting? 

The semi truck you’re considering must fit all your requirements. You’ll need a refrigerated truck if you’re carrying perishable goods. Otherwise, a dry van would do. A flatbed semi truck may be your best choice if you carry cargo too large for traditional enclosed trailers. 

2. Engine

The engine is the truck’s powerhouse, so it must be in top condition. If you’re buying a used truck, request its maintenance records and determine if the previous owner stayed on top of oil changes and services. Check engine hours for high idle times, which can cause wear that mileage won’t show. If you’re buying a semi truck that needs a new engine, choose a replacement with more than 400 horsepower to improve its longevity.

3. Tires

Tires are a recurring expense in trucking, so choose a semi truck with good rubber to save thousands of dollars upfront. Check for the following in your potential semi truck’s set:

  • Wear patterns: If they’re irregular, the truck might have alignment issues.
  • Tread depth: All the tires must have at least 4⁄32 of an inch when measured from the major tread groove.
  • DOT code: Tires over six years old may need to be replaced soon, especially if the truck has high mileage.
  • Tire type and size: Mismatched tire types and sizes can cause performance and wear issues, especially if they’re on the same axle. 

Tire blowouts are one of many common issues in heavy vehicles that you can avoid with a thorough inspection. 

4. Paperwork

A truck in top condition can still be a bad investment. If you’re buying a used truck, ensure its title is clear of liens. Check its inspection reports and service logs for major repairs or damage. Ensuring all the paperwork is in order is crucial, especially if you get an auto loan or insurance. 

Driving Toward a Smart Investment

A successful purchase involves choosing the truck that matches your needs and performing a meticulous, hands-on inspection. Take your time with the latter, and don’t hesitate to ask questions about your observations. Remember, you’re not just buying a semi truck. You’re making a strategic investment for your future.
