If you’re looking for a dump body for your work truck, two names come up often: CM Truck Beds and Knapheide. Both are well-known manufacturers with solid reputations, but they serve different buyer priorities. This guide breaks down the key differences so you can make the right call for your fleet or personal work truck.
Who Makes CM and Knapheide?
CM Truck Beds is a Texas-based manufacturer known for heavy-duty steel truck beds, flatbeds, service bodies, hay beds, and dump bodies. CM focuses on straightforward, tough-built units designed for ranchers, contractors, and oilfield workers across the South and Great Plains. Their products are built for hard use — not luxury, but reliability.
Knapheide is a larger national manufacturer based in Illinois. They offer a broader product line including dump bodies, utility beds, crane bodies, and service bodies. Knapheide has a large dealer network and is often spec’d into commercial fleet orders. They lean toward fleet buyers and municipal buyers who value standardization and long parts chains.
CM Dump Bodies: What You’re Getting
CM’s dump bodies are built with high-strength steel and designed to handle the kind of abuse that comes with job-site use in Texas and Louisiana. Key features include:
- Heavy-gauge steel sides and floor — holds up under gravel, caliche, topsoil, and demolition debris
- Multiple hoist configurations — scissor-lift and underbody hoist options for different truck chassis
- Tailgate options — barn door and spreader gate configurations available
- Bed lengths and widths — sized for 1-ton, Class 4, and Class 5 trucks (Ford F-350 through F-550, Ram 3500 through 5500, Chevy Silverado 3500HD and 5500HD)
- Texas-ready finish — powder coat or primer finishes designed for Texas heat and humidity
CM dump bodies are popular with landscapers, roofers, contractors hauling gravel, and agricultural operations where a dependable dump on a 1-ton or Class 5 chassis gets the job done without overpaying.
Knapheide Dump Bodies: What You’re Getting
Knapheide’s dump body lineup is broad. Their standard and heavy-duty dump bodies are available in a wide range of lengths and weight ratings. Key features include:
- Reinforced floor design — ribbed steel floor construction for rigidity under heavy loads
- Telescoping hoist options — available in scissor, telescoping, and underbody variants
- Corrosion protection — galvanized options available for buyers in humid environments
- National parts availability — because Knapheide has dealers nationwide, parts and service are often easier to source in larger metros
- Fleet-spec ordering — large buyers can order standardized configurations across a fleet
Knapheide tends to be a stronger fit for municipal fleets, large commercial operations, and buyers who prioritize a long dealer network for maintenance.

|---|---|---|
| Origin | Texas-based manufacturer | Illinois-based manufacturer |
| Primary Market | Ranchers, contractors, ag, oilfield | Fleet buyers, municipalities, commercial |
| Steel Grade | Heavy-gauge high-strength steel | Reinforced steel, galvanized options |
| Hoist Types | Scissor-lift, underbody | Scissor, telescoping, underbody |

| Lead Time | Typically shorter through TX dealer | Varies by region and spec |
Which Is Better for Texas and Louisiana Buyers?
For most buyers in Texas and Louisiana, CM is the stronger everyday choice for a few reasons:
- CM is built by Texans for the Texas market — the specs reflect what ranchers, contractors, and oilfield workers here actually need
- Dealer support through a local Texas truck body dealer is typically faster for installation and warranty
- Pricing for single-unit buyers is generally more accessible than going through a large fleet channel
Knapheide makes sense if you’re buying multiple units through a fleet account, need galvanized options, or your operation already runs Knapheide equipment and you want uniform parts across the fleet.
What Trucks Do CM Dump Bodies Fit?
CM dump bodies are available for most popular chassis:
- Ford F-350, F-450, F-550 (most common in Texas for dump body installs)
- Ram 3500, 4500, 5500
- Chevy Silverado 3500HD, 4500HD, 5500HD
- GMC Sierra 3500HD, 4500HD
The right dump body size depends on your cab-to-axle measurement. Call our team and we’ll match the body to your truck’s spec so the install goes clean and passes weight compliance.
