a service body truck and a truck cap side by side

Enclosed steel service body trucks have long been the standard for service fleets. But for many fleet managers, the downsides are becoming harder to ignore.

Many service-oriented fleets are now rethinking whether they truly need the weight, complexity, and operating costs that come with them.

For technicians focused on diagnostics, installs, repairs, and daily dispatch work, flexibility and workflow often matter more than maximum payload.

Move Beyond the Limitations of a Steel Service Body Truck

That’s where Sterling’s low-profile fiberglass truck cap comes in. With a lower purchase price and lower long-term costs, it’s time to consider a smarter alternative built for modern service fleet.

Sterling’s truck caps give service fleets a lighter, more adaptable mobile workspace — without sacrificing durability or functionality.

Ideal for telecom, utility, mechanical trades, and field service teams.

  • Long lead times – Fleet Managers report having to Wait 6 – 14 Months
  • Fuel Bills Are Over Budget
  • Rust and condensation is Damaging Tools

  • Higher Replacement Costs
If you are looking to eliminate these problems, we can help!

A Better Long-Term Fleet Investment

Sterling’s truck caps offer a lower-cost, fleet-ready solution without the weight, complexity, and long lead times of traditional service body trucks.

Starting at approximately $10,000 USD / 13,800 CAD for an empty cap, each unit can be customized to match your operation.

Our most popular configuration — the Contractor Package for 6.5′ and 8′ beds starts at approximately $18,000 USD / $24,000 CAD and includes:

  • Heavy-duty pull-out BedSlide
  • Aluminum shelving in the side access doors
  • Interior and exterior work lighting
  • Backup camera integration
  • High-security locking system
  • Keyless remote entry for all three doors

Think Beyond a Single Truck Lifecycle

Unlike traditional service bodies, Sterling’s slip-in caps can be easily transferred to another pickup truck. Your techs don’t even have to remove their gear!

Note: This chart assumes the service body is replaced on the existing truck chassis. However, many fleet managers report
that the chassis often needs replacement at the same time, which can significantly increase total lifecycle costs.
