How many miles is too many on a used semi truck?

A well-maintained semi truck engine is built to run 750,000 to over 1,000,000 miles before a major overhaul. Mileage alone isn't the right filter — service history, engine condition, and whether the truck has had any major powertrain work matter more. A 600,000-mile truck with documented maintenance and recent engine work can be a better buy than a 400,000-mile truck with no service records.

Should I buy a day cab or sleeper semi truck?

It depends on your operation. If your routes are regional or local and drivers return home nightly, a day cab is the more practical and cost-efficient choice — it's lighter, simpler, and less expensive to maintain. If you're running long-haul or OTR freight where drivers spend nights on the road, a sleeper provides the comfort and compliance with hours-of-service regulations that an OTR operation requires.

Can I search semi trucks by location on Comvoy?

Yes. Comvoy lets you filter semi truck listings by location so you can find trucks available near you or in a specific state — reducing transport costs and making it easier to inspect before you buy. You can also filter by make, model year, mileage, and price to narrow results to your exact spec.

How much weight can a semi truck carry?

The legal limit for a loaded semi-truck in the US is 80,000 pounds, though the actual capacity can vary depending on the truck and trailer configuration.

How many gears do semi trucks have?

They can have up to 18 gears, providing the necessary torque and power for hauling heavy loads efficiently.

How much fuel do semi trucks use?

Fuel efficiency varies depending on engine size, load weight, and driving conditions, but expect lower mpg than cars, typically around 5-8 mpg.

Do you need a special license to drive a semi truck?

Yes, a Commercial Driver's License (CDL) with specific endorsements is required to operate a semi-truck legally.

What are the challenges of being a truck driver?

Long hours on the road, loneliness, traffic congestion, and dealing with varying weather conditions are some of the challenges truck drivers face.

What kinds of trailers can semi trucks haul?

Semi trucks can haul many different types of trailers. The most commonly hauled trailers are dry vans, reefers, flatbeds, tankers, and lowboys.
