The CM SK is the most common steel service body on Texas work trucks, and the Pronghorn service deck is the premium alternative buyers step up to when they want a heavier, better-finished body. We stock and install both, so here’s the honest breakdown of who should buy which.

CM SK vs Pronghorn Service Deck

Buy the CM SK If…

• You need a proven service body at the best price per truck — especially across a fleet.
• Payload is tight and you want less body weight on the frame.
• Parts and replacement doors are easy to get anywhere in Texas.
• You want the lowest total cost to get a working service truck on the road.

Buy the Pronghorn If…

• The truck runs hard daily and you plan to keep it a decade.
• You want heavier steel, better welds, and a finish that holds up to oilfield abuse.
• Compartment depth and layout matter more than price.
• You’re replacing a body that rusted or cracked and don’t want to repeat it.

Where the Money Actually Goes

The price gap between these two isn’t marketing. Pronghorn uses heavier material and a more involved finishing process, and you feel it in door fit, compartment sealing, and how the body looks after a few Texas summers. The CM SK is not a cheap body — it’s a very good body built to a price. For a contractor rotating trucks every four or five years, the CM SK is often the smarter financial decision. For an owner-operator who buys once, the Pronghorn usually is.

Payload and Fitment

Both add real weight over a pickup bed. On a single-rear-wheel 3/4-ton, the lighter CM SK preserves more of your rating; on a one-ton dually either works. Both need the right cab-to-axle length — see 56-inch vs 60-inch CA fitment. Compare the SK against CM’s other bodies in our CM SB vs CM SK comparison and CM SK vs CM SRX comparison.
