2009 Chevrolet C6500 Box Truck 13’6: Ultimate Guide

If you’re hunting for a dependable medium-duty truck that delivers power, payload, and proven durability, the 2009 Chevrolet C6500 Box Truck 13’6 might just be your best-kept secret. Despite being over a decade old, this workhorse still finds a home in countless delivery fleets, contractor businesses, and moving companies.

But why does this aging juggernaut still get the nod over newer, shinier options? And what does “13’6” actually mean? This ultimate guide unpacks everything—technical specs, real-world applications, ownership costs, and buyer advice.

Overview of the 2009 Chevrolet C6500 Box Truck 13’6

Part of Chevrolet’s TopKick series, the C6500 is a Class 6 medium-duty truck built on a strong chassis. It was manufactured in collaboration with General Motors and Isuzu to serve a variety of commercial needs—from box delivery trucks to utility rigs.

This particular model often comes equipped with a Duramax diesel engine, a robust Allison transmission, and a box cargo body, making it an ideal solution for businesses that need both strength and versatility.

What Does 13’6 Mean on the Box Truck?

The term “13’6” refers to the height of the truck, including the box. In most states and federal transportation guidelines, the maximum legal height for commercial vehicles is 13 feet, 6 inches. This makes the C6500 compliant with most bridge and overpass clearances, particularly on highways and major roads.

However, caution is needed when operating on rural roads or under low-hanging utility lines.
