"More Trailer For Your Money"

8.5 x 22 Haulmark Grizzly HD Contractor Edition 12K Enclosed Cargo Trailer – Ready To Work!

.080 PolyCor

The Trailer Source Contractor Edition isn't just a random list of upgrades; it is the "Greatest Hits" album of hundreds of custom builds.

For years, contractors came to Trailer Source with the same problem: standard trailers were failing them. They were blowing out floors with pallet jacks, bowing walls with heavy racking, and working in the dark because standard dome lights didn't cut it. After building hundreds of one-off custom units to solve these specific problems, Trailer Source took the most critical, "must-have" upgrades and standardized them into the Contractor Edition.

The Evolution of the Build

Solving the "Soft Floor" Problem Contractors were tired of standard 3/4" floors soft-spotting under the weight of heavy tool chests or palletized materials.

• The Custom Fix: We started doubling the floors and tightening the steel crossmember spacing.
• The Contractor Edition Standard: You now get 12" on-center spacing and a Double 3/4" PlexCore floor (1.5" total thickness). It’s essentially a bridge deck inside a trailer.

Ending the "Wall Sag" Standard 3/8" walls couldn't support heavy shelving or E-track without eventually stripping out or warping.

• The Custom Fix: We began lining trailers with thicker material so contractors could actually bolt things to the walls.
• The Contractor Edition Standard: 3/4" Sidewalls are now standard, allowing you to mount your entire shop directly to the "skeleton" of the trailer with total security.

The "Midnight on the Job Site" Fix Working late or starting early meant fumbling with flashlights because 12V dome lights are notoriously dim.

• The Custom Fix: We spent years installing aftermarket light bars and scene lights for crews.
• The Contractor Edition Standard: We integrated Three 36" Slim Line interior lights and Three 24" 9,000-lumen exterior scene lights. It turns the trailer and the surrounding 20 feet into a daylight workspace at the flip of a switch.

True Mobile Power Contractors were tired of "daisy-chaining" extension cords through the door just to charge batteries.

• The Custom Fix: We started installing 30-amp sub-panels and motorbase plugs for "one-plug" power.
• The Contractor Edition Standard: A full 30-amp service package with a 25' cord and interior outlets is built-in, so your mobile shop is "plug-and-play" the moment you hit the job site.

THE TRAILER SOURCE "CONTRACTOR EDITION" UPGRADES

This exclusive package transforms the trailer into a self-contained, high-capacity mobile facility.

Structural Overbuild

• 12" On-Center Floor & Wall Crossmembers: Standard trailers use 16" or 24" spacing. This ultra-dense framing creates a "solid steel" foundation that prevents floor flex and wall bowing under extreme machinery loads.
• Double 3/4" PlexCore™ Flooring (1.5" Total): Two layers of water-resistant, high-performance decking. This is designed for high-PSI loads like pallet jacks or heavy machinery that would crush a single-layer floor.
• 3/4" PlexCore™ Sidewalls: Doubling the standard thickness allows you to mount heavy-duty shelving, tool racks, or workbenches directly to the walls with maximum screw-holding power.

High-Output Lighting & Power

• 30-Amp Electrical Suite: Includes a motorbase with twist-lock connect, 25' power cord, 30A service panel, and two 120V outlets. This is "plug-and-play" power for chargers, saws, and diagnostic equipment.
• LED Scene Lighting (9K Lumens): Three 24" exterior-mounted scene lights provide a massive wash of 27,000 total lumens. This turns the area around the trailer into a daylight workspace at midnight.
• Interior Lighting Overhaul: Three 36" Slim Line accent lights, two 4' LED ceiling wrap fixtures, and a marine battery with an exterior box to run it all independently of your truck.

Climate & Utility Readiness

• Roof Vent (Framed/Wired for A/C): The roof is reinforced and pre-wired, allowing you to drop in a 13,500 or 15,000 BTU A/C unit without structural modifications.
• HD Ramp w/ Spoiler: A reinforced rear ramp door with a built-in rear spoiler that protects the integrated loading lights and improves aerodynamics.

CORE GRIZZLY HD FEATURES (THE FOUNDATION)

Exclusive DuraCage™ Frame Construction

The chassis is a proprietary cage design using fully boxed high-tensile steel tubing for the main rails, vertical posts, and roof bows.

• The Benefit: It creates a commercial-grade vault that resists the twisting and "racking" common when navigating uneven job sites or hauling heavy, off-balance equipment.

Heavy Duty Dexter® Torflex® Axles (12K/14K GVWR)

Independent rubber torsion suspension with E-Z Lube® hubs.

• The Benefit: This suspension absorbs road shock at each wheel, protecting your tools and electronics from "trailer bounce." It provides a planted, stable tow whether the trailer is empty or fully maxed out.

ArmorTech™ & Z-Tech™ Protective Coatings

A dual-layer defense system: ArmorTech on the A-frame and rear hoop; Z-Tech undercoating on the entire chassis.

• The Benefit: ArmorTech acts as a permanent "bed-liner" barrier against rock chips and road salt, while the undercoating prevents corrosion from the bottom up, ensuring a 15+ year lifespan.

8,000 lb. Square Tube Drop-Leg Jack

• The Benefit: Speed and strength. The drop-leg design allows you to set the jack instantly without excessive cranking, and the 8K rating effortlessly handles the heavy tongue weights of a loaded contractor trailer.

WHY THE CONTRACTOR EDITION?

This is a "one-and-done" investment for professionals who cannot afford equipment failure or downtime.

THE MOBILE WORKSHOP: 30A Power & High-Output LEDs

• Stop working in the dark. Between the 9,000-lumen scene lights and the 4' interior wraps, you have a better-lit workspace than most stationary shops.

THE DENSITY: 12" O/C Framing

• Built for Pallets & Machinery. The structural frequency of the 12" centers combined with the 1.5" thick floor means you can load skids of material with total confidence.

THE CLIMATE: A/C Prep & Ceiling Liner

• Command Center Ready. The ceiling liner and A/C framing mean this trailer is ready to be converted into a site office or climate-controlled shop at any time.
