These capacities, dimensions and mileage are approximations and may vary by manufacturer. Miles per gallon may vary depending on load, terrain and driving factors. Commercial trucks such as Freightliner, cargo vans or box trucks are built to last a long time. After traveling 100,000 miles, light trucks generally have three to five years of optimal operation, and medium trucks can travel between 300,000 and 350,000 miles.
But will you get good mileage like what a new truck would give you? If you're not sure how many miles a used truck can last, you're in the right place. When it comes to a truck, you know that a truck that runs on a gasoline engine can travel up to approximately 155,000 miles, while a truck that runs on diesel can provide you with a mileage of 200,000 miles. If you find a truck that shows low mileage, your best bet would be to invest the money in another truck.
