7 Features That Make Double Diamond the Best Custom Flatbed Truck Bed on the Market

Not all flatbed truck beds are created equal. While production brands focus on pumping out volume at the lowest possible cost, Double Diamond flatbeds are designed by people who actually use flatbeds every day. That real-world experience shows in every engineering decision.

Here are the 7 features that make Double Diamond flatbeds the best on the market — and why customers consistently say they're glad they waited for one instead of settling for a production bed.

1. The 2.5" × .120 Wall Headache Rack

Most flatbed brands treat the headache rack as an afterthought. Double Diamond treats it as the most critical structural component on the bed.

What makes it different:

• 2.5" × 2.5" square tube with .120 wall thickness — over twice the strength of competing designs
• Designed to not block dome light cameras — you maintain full visibility of your bed from the cab
• Saves bed space compared to formed sheet metal designs (Bradford Built, Hillsboro)
• Clean, uniform aesthetic that looks professional for years

Why it matters: Your headache rack is what stands between a shifting load and your rear window. When a 2,000-pound pallet slides forward during a hard brake, you want 2.5" of .120 wall tube behind you — not thin-wall rolled tube or stamped sheet metal.

2. 6×3 Tube Sides — Strongest in the Industry

While every other brand uses ⅛" formed sheet metal for their sides (which dents the first time you bump it with a forklift), Double Diamond uses 6" × 3" heavy-wall tube sides.

What makes it different:

• Superior strength to any other option on the market
• Carve-out above the tire allows for full suspension travel
• Won't dent, bend, or deform under normal working conditions
• Hides the frame completely for a proportional, professional look

Why it matters: If you're loading and unloading daily, your bed sides take constant abuse. Sheet metal dents. Tube doesn't. It's that simple.

3. Inset D-Rings — The Customer Favorite

This is consistently the #1 feature customers mention when asked what they love about their Double Diamond bed.

What makes it different:

• D-rings sit flush with the bed surface instead of protruding above it
• Straps route cleanly without catching on raised hardware
• No more strapping over the side and dinging up your powdercoat
• No more bending bed rails with strap tension

Why it matters: You strap things down every day. Every single time you throw a strap, you interact with your D-rings. When they're inset, the experience is effortless. When they protrude (like every competitor), it's a daily frustration you learn to tolerate.

4. Unlimited Color Options

Walk into any dealer and ask for a Bradford Built, CM, or ProLine flatbed. What color options do you get?

Black. That's it. Maybe occasionally white.

Double Diamond offers:

• Any color — literally any color you can imagine
• Exact color matching to your truck's factory paint
• 2-tone bed rails for a premium, custom look
• Unique colors nobody else has — stand out at the job site or the truck meet

Why it matters: Your truck is an extension of your business and personality. A color-matched flatbed looks intentional and professional. A generic black bed on a red truck looks like an afterthought.

5. Backup Camera & Parking Sensor Integration

This is something no production bed brand offers — because it requires custom engineering for each build.

What makes it different:

• Backup cameras integrated directly into the bed design
• Parking sensors wired cleanly (no exposed wires or aftermarket look)
• Designed from day one, not hacked on after the fact

Why it matters: Modern trucks come with advanced safety tech. When you replace the factory bed with a flatbed, you lose those features — unless your bed is designed to accommodate them. Double Diamond is the only brand that engineers this into the build.

6. Modular Toolbox & Storage System

Production beds give you a standard toolbox location and size. Take it or leave it.

Double Diamond builds your storage solution around your actual workflow:

• Any number of toolboxes — one, two, four, whatever you need
• Any size — from small parts bins to full-width underbody boxes
• Fixed or removable — change your configuration as your needs evolve
• Step fenders — adds a handy step behind the toolbox for easy bed access
• Octagon cutouts — incremental strapping points along the entire bed length

Why it matters: Everyone uses their truck differently. A rancher needs different storage than a contractor. A hotshot hauler needs different tie-down points than a landscaper. Your bed should be built for YOUR work, not for the average of everyone's work.

7. World-Class Craftsmanship Guarantee

Double Diamond doesn't hire the cheapest labor and churn out units. They hire exceptional craftsmen and maintain strict quality control.

What this means in practice:

• Nothing leaves the shop that doesn't look exceptional
• Welds are clean, consistent, and ground where appropriate
• Powdercoat is applied properly with full surface prep
• Fit and finish rival beds costing twice as much
• Every detail is checked before delivery

The production bed reality: Companies like CM and Bradford Built are focused on price. To hit their price points, they hire the lowest-skilled labor available and focus on throughput. The result is inconsistent quality, visible weld spatter, and "good enough" finishing.

The Bottom Line

A flatbed truck bed is something you use every single day. It's not a purchase you make once and forget about — it's a tool you interact with constantly. The small differences between a Double Diamond and a production bed compound over thousands of uses:

• Straps that route cleanly (inset D-rings)
• A camera view that isn't blocked (engineered headache rack)
• Sides that don't dent (tube vs sheet metal)
• A color that matches your truck (unlimited options)
• Storage that fits your workflow (modular system)
• Safety tech that still works (integrated cameras/sensors)

These aren't luxury features. They're practical engineering decisions made by people who actually use flatbeds.
