New Engineered Beam Fabrication Center
We purchased this building in Mt. Pleasant in the spring of 2021, and are currently in the process of renovating it into a brand new Engineered Beam Fabrication Center. As our Patent Protected ENGINEERED BEAM TECHNOLOGY that we use on our flagship trailer models has continued to grow, and as we’ve begun adding these custom beams to more of our trailer lineup, it was time to expand our production facilities to enable us to produce these beams in-house faster and more efficiently.
Tune in below for the full story and watch along as Jacob gives a tour of the new facility. More updates on this coming soon!
Do you know trailer brakes? Diamond C offers 3 types: Electric Drum, Electric Over Hydraulic Drum, and Electric Over Hydraulic Disc brakes.
Below are some helpful tips for choosing the right brakes for your trailer.
Electric Drum Brakes
Electric drum brakes are the utility and flatbed trailer industry standard for trailer braking systems. Electric drum brakes are controlled by an in-cab controller that comes standard on many of today’s trucks and SUVs. Electric drum brakes are well suited for most general use applications – trailers that are used moderately within their capacity and towed with some regularity. If you plan to use your trailer aggressively in relation to its PAYLOAD CAPACITY and plan to tow it on a more regular basis, then keep scrolling to see our electric over hydraulic brake options below.BREAK-IN PERIOD MANUAL
How to Burnish Your Trailer Brakes
Electric Drum Brakes require a proper BREAK-IN PERIOD to achieve full performance. Watch below for a step by step guide from Lippert Axles on proper burnishing procedure.
Electric Over Hydraulic Drum Brakes
Electric over hydraulic drum brakes are similar in that they are controlled by the same in-cab controller as standard electric drum brakes. They also share the same actual drum braking components. Where they differ is that instead of electromagnetic force being utilized to help slow the trailer, the electric pulse from the to tow vehicle activates a small hydraulic pump that sends fluid into the drum to forcefully apply braking pressure.
Electric Over Hydraulic Disc Brakes
Electric over hydraulic disc brakes are similar to both previous brake types in that they are operated by an in-cab controller. However, disc brakes are what avid heavy duty trailers users would describe as “the ultimate” when it comes to trailer braking systems. They use the same hydraulic force we mentioned in electric over hydraulic drum Brakes for better braking pressure, but where they differ is the use of disc (rotor) / caliper braking components in lieu of the drums. Disc brakes provide increased stopping power over drums. In addition, disc brakes are more cost effective when it comes to upkeep and preventative maintenance over time. With disc brakes you are able to replace individual brake pads, versus replacing the more costly full drum braking assembly.
If you are a gooseneck HOT SHOT trailer user who puts in a lot of miles over the years, we highly recommend hydraulic disc brakes.
Benefits of Hydraulic Disc Brakes:
- Last longer
- Stop faster
- Cheaper to maintain for high mileage trailers
16K Disk Brakes
In early 2021 we announced the 16K Electric over Hydraulic Disc Brake option. This industry-first option has been a long time coming, and is the result of a 2 year collaborative journey between Diamond C and LIPPERT. These 16K Disc Brakes are now available on all FMAX216, SDX216, & PX216 models.

When you are looking for a cost-effective way to gain a little extra cubic body room on you DUMP TRAILER, but don’t really want taller solid sides, the Raised Front & Board Bracket option is a great in-between.
Utilizing a 2″x6″ pressure treated pine board, the option also offers additional protection to the top rail of your trailer so that when you or your crew are loading material over the side and happen to bump it with a bucket, you aren’t directly contacting the DM POWDER COATED surface.
This option can also be added in combination with one of our dump TALLER SIDE height options.
Diamond C EQUIPMENT TRAILERS come with a choice of heavy duty or general duty flip-knee ramp options.
Extra Wide 24″ HD Flip-Knee Ramps
For extreme loading and unloading, outfit your equipment trailer with our 24″ wide x 60″ long HD ramps. These extra wide ramps are spring-assisted, so lifting and lowering is made easy even by a single person.
Our heavy duty ramps are constructed with 4″ channel side supports and 2″ square tube cross supports for maximum support. The gradual expanded metal loading surface and angle makes loading and unloading a breeze.
60″ Flip-Knee Ramps
These 4″ channel, spring-assisted ramps are offered on most equipment trailer models The support knee adds durability and extra support when loading heavier equipment.
XDR Extreme Duty Flip-Knee Ramps
We also offer XDR RAMPS – these extreme duty ramps were specifically designed to haul heavy concentrated equipment and machinery such as backhoes and excavators. Learn more about them HERE. (Available on all all GOOSENECK, PINTLE HITCH, and STEP DECK trailers).
Our 7 gauge super duty dump body package is an ideal option for those who need their trailer to perform regardless of the grueling work they do. The extra strength body is a must have for commercial and construction workers who require that extra toughness and durability that a thicker dump body can provide for their on-site jobs. Our dump trailers already feature UP TO 2X WIDER than industry standard top rails and side upright supports, and this 7 ga upgrade package pushes the limits even more for maximum dump trailer strength and dependability that professionals require.
Offered as an available upgrade on models LPD and LPT, this durable body upgrade can even be combined with taller SIDE HEIGHTS for maximum customizability. This extra strength body upgrade is a must have for who require that extra toughness and durability that a thicker dump body can provide.

Diamond C vs…
If you’re reading this, chances are you’ve already done some of your own reading about which manufacturer claims to have the best dump trailer on the market. Chances are, you might have even done some research of your own comparing Big Tex, PJ, MaxxD, Load Trail, Lamar, and some of the other trailer brands out there to see how they stack up to Diamond C.
Maybe you’ve even watched a few of our YOUTUBE videos showcasing our trailers being used in the real world, or perhaps you’ve even spent some time on our SOCIAL MEDIA pages browsing through our posts about our trailers, team members, and what we do in our local community.
Maybe you still have questions about why you should consider a Diamond C instead of the alternatives available to you. Maybe you’ve already made up your mind and are leaning towards a different brand, or maybe you’ve spent some time pricing out a model on our TRAILER CONFIGURATOR but are still having reservations or are on the fence.
Whatever your situation may be, let’s take a few minutes to walk through every important standout feature available to you on our dump trailers, but perhaps more importantly, the WHY behind what makes us so confident in saying that a Diamond C dump gives you the best long-term investment and feature-set to take your needs far into the future as a dump trailer owner.
With that, let’s get started.
(Prefer to watch instead of read? No problem – check out this informative video tour below from our very own Jacob Crabb, and watch and follow along as he shows our dump trailer lot right here at the factory and reveals the details, behind the scenes, and highlights the most important features and must-have options for our entire dump lineup).
What dump trailer models are available?
We offer a comprehensive lineup of premium dump and gooseneck dump trailers, ranging from light duty single axle residential models all the way to heavy duty, dual tandem wheeled commercial and construction models. Our dump trailer models range from 6,000 lb GVWR all the way up to 30,000 lb GVWR. (If you need a refresher on what GVWR means and how it differs from Payload check out THIS POST).
Let’s start with our light duty dumps and work our way up the the heavier duty models.
Light – Medium Duty Models (Under 10K GVWR)
Base MSRP: $7,310
GVWR: 6,000 lb
Base MSRP: $8,185
GVWR: 7,000 lb
Base MSRP: $9,855
GVWR: 9,890 lb
Our trio of light-medium duty dumps are designed to perfectly compliment most half ton pickup trucks on the market. The GST is ideal for smaller projects around the house or farm, the GDT excels as a small landscaper’s trailer for hauling mulch, dirt, and debris, while the medium duty MDT is a great solution for light commercial use.
For more in-depth specs feel free to check out each model’s product page, but here are the highlights you need to know:
Standout Included Features
3-Stage Telescopic Cylinder Hoist
We’ll cover this in more detail further down the page – but here’s what’s most important: Telescopic Dump Cylinders provide greater lifting power and can handle unevenly distributed loads significantly better than traditional scissor lift hoists, which you’ll find on most comparable dump trailers on the market.
Low profile 6″ I-Beam Frame
Most of our competitors use 5″ Channel or 6″ x 2″ Rectangle Tubing for their small dump frames. Our low profile sturdy 6″ I-Beam design makes for a significantly stronger and longer lasting trailer frame.
Demco EZ-Latch Adjustable Couplers
This unique COUPLER DESIGN automatically latches when placed over a hitch ball and is entirely maintenance-free as the coupler doesn’t require any greasing or adjustments. Demco cast couplers are made from sturdy steel and feature a durable primed finish.
3″ Top Rail and Side Uprights
Most manufacturers use 2″ sides and uprights on their 5-10K dump trailers. Not us. Our trio of small dumps all use a beefy 3″ rail which allows your trailer to take more abuse and not become deformed over time from loading over the side of the trailer with a bucket, or from the added stress over years of hauling rocks and gravel inside the body.
Tarp Brackets and Full Tarp Included
Ever been heading down the road with a full load of debris and notice you are loosing material out the top of your dump? We hear your frustration – all Diamond C dumps feature tarp brackets and a heavy duty black mesh tarp standard at no additional cost.
Most Popular Upgrades
This option utilizes a 2″x6″ pressure treated pine board which offers additional protection to the top rail of your trailer so that when you or your crew are loading material over the side and happen to bump it with a bucket, you aren’t directly contacting the paint or damaging the side of the trailer.
Need to run double duty on the job site and haul something? No problem – add 60″ rear slide-in ramps to haul small machinery and equipment, then securely tuck them back into the dump frame when not in use.
Our small dump trio all come standard with 12 ga, 18″ tall sides, but can easily be upgraded to 44″ with a more durable and thicker 10 ga body. This is a great option if you’re needing to haul lots of trash or debris regularly. (Note: Single axle model GST can be built with a maximum of 32″ sides)

Our four heavy duty dump trailer models are the muscle and power behind many contractor’s and construction manager’s fleets. These heavy duty commercial grade dumps are jam packed with all our latest innovations, features, and intelligent designs to make your life easier while on the job.
- Model LPD is THE original heavy duty low profile dump trailer that Diamond C brought to the market in 2008 (there’s an interesting STORY behind that). Chances are if you’ve seen a Diamond C dump on the road in the past decade or so, it was an LPD.
- Model LPT is the telescopic cylinder brother of the best selling LPD design. Telescopic hoist = unparalleled lifting power and ease.
- If it’s versatility you’re after, model DOD has your back. With it’s extra wide deck over design, your choice of bumper pull or gooseneck, up to 24K GVWR, and handy fold-down sides, it’s the perfect choice if you’re needing to frequently side-load material in addition to your everyday heavy duty hauling.
- Model WDT – the big boy. This beast of a dual tandem gooseneck dump features massive 44″ sides, 96″ bed width, up to a 22 cubic yard capacity, and can be built with a telescopic hoist and a 13HP gas power engine for maximum dumping power. You won’t find any manual roll-back tarps here – we include an electric tarp standard. Simply push a button and your load is covered automatically.
For more in-depth specs feel free to check out each model’s product page, but here are the highlights you need to know:
Standout Features & Upgrades
GVWR Upgrade Packages
All these heavy duty models offer GVWR upgrade packages, which allow you to customize your trailer with powerful upgraded axles for significantly more loading power. Models LPD, LPT, and DOD come standard with dual 7K axles rated at a 14,900 lb GVWR, but are upgradable with 8K, 10K, or even triple 7K axles to bring the GVWR up to 24,000 lb. Most of these upgrade packages include superior SUSPENSION SYSTEMS as well (like Torsion Axles).
Model WDT is a dual-tandem beast that clocks in at 25,000 lb GVWR, but can be built with dual 16K axles for the most extreme loads when you need a 30,000 lb rated dump trailer.
Engineered Beam Technology
New for our dump lineup in 2021 is adding our patent protected ENGINEERED BEAM TECHNOLOGY, which we adapted from our GOOSENECK TRAILER line to custom fit our dumps. We build our engineered beams in-house, which allows us full customization and control over the trailer beams and frames. The result is a significantly stronger, taller, and lighter beam that gives you a much better strength-to-weight ratio than a traditional 8″ I-beam equipped dump trailer.
Add a Gooseneck Package
Our dump GOOSENECK PACKAGE upgrade utilizes the same technology found in our engineered beams. This 1-piece smooth engineered 12″ curved neck design distributes force throughout the neck so there is no concentration of stress in the corners. This option includes dual 12K jacks, a massive full-width diamond plate storage box, and a BX-1 coupler.
Include a SHOCKER HITCH COUPLER for that smooth air ride experience. This coupler includes an airbag to absorb extra energy, which saves on wear and tear on your trailer (and on your back – trust us. You’ll thank yourself later after a long day of hauling).
Maximize your storage potential with a Deck on the Neck
Need extra storage while on the job? Our bolt-on/weld-on Deck on the Neck can be fitted to any of our heavy duty dumps with a gooseneck package to give you an additional 56 sq ft of storage. The deck includes LED clearance lights and plenty of tie down options.
7 ga Body & Sides
The beefy 7 GA DUMP BODY PACKAGE extra strength body is a must have for commercial and construction workers who require the extra toughness and durability that a thicker dump body can provide for their on-site jobs.
4″ Top Rail and Side Uprights
You won’t find any skimpy 2″ sides and uprights anywhere on our 14K and up dump trailers – we use a beefy 4″ top rail and side uprights for maximum toughness. The wider and deeper uprights provide far more support up the side of the trailer, which makes the whole dump body significantly stronger and last much longer.
Overlapped Central Seam
The dump body innovations don’t stop there – we also feature a central seam overlapped floor design on all our dump trailers. This makes for a much tougher joint where the floor plate meets, but keeps the seam out of the corners. We’ve found through testing that a 1 piece solid sheet of metal on the dump bed floor welded to the corners is a bad design, as it causes moisture and rust to form in the corners. Instead, we use 2 sheets – the dump side and floor is a single sheet of 10ga / 7ga metal and the seam is in the middle. We don’t butt the sheets in the middle like some do, we overlap it (at least 3″ on all dumps) so that the weld doesn’t ever break apart. It’s almost indestructible – this is a big deal for long term durability. Small detail, BIG overall impact.
Up to 44″ Side Heights
Heavy duty models LPD and LPT come standard with 24″ tall sides, but can be configured with 32″ or even 44″ tall sides to gain every last cubic feet. This is a great option if you regularly have to haul trash or lots of debris from the job site. (Just like on our the light duty dump models, we also offer a 2×6 board bracket option to protect the top of the trailer from loading bucket bumps).
All 4 of our heavy duty dump models can be outfitted with electric-over-hydraulic DISC BRAKES. These disc brakes utilize hydraulic pressure to provide superior stopping power when compared to regular drum brakes. They are also more cost effective when it comes to upkeep and preventative maintenance over time.
Gates & Ramps
All our dumps feature a handy 3-way gate standard for multiple dumping options, and our heavy duty models feature standard 72″, 78″ or 90″ Rear Slide-In Ramps (depending on the model). Make your dump trailer twice as versatile and valuable by being able to haul equipment while on the job. Whether it be a small tractor, a skid steer, or a mini-excavator, your dump trailer can handle it.
Heavy Duty Fenders
An often overlooked part of heavy duty hauling are the trailer FENDERS – a durable fender is a must-have to protect your wheels and dump sides from accidental bumps. All our dumps come standard with durable 14 ga diamond plate fenders, and for those contractors and work crews whose environment requires equipment outfitted with the toughest features known to man – we offer the super heavy duty 3/16″ diamond plate fenders. These also pair great with the 215/75R17.5 HEAVY DUTY TIRE UPGRADE.
HD V-Tongue Storage Lid/Box
A Diamond C original and a best seller since the day we launched it, this intelligently crafted storage option offers maximum storage space for jacks, tools, straps, etc. Constructed with 3/16″ Diamond Plate, this lid also doubles as bonus deck space. The box safely houses the battery and hydraulics systems and still leaves ample room for storage. You’ll find this popular option on our LPD and DOD.
Heavy Duty Dump Series Videos
Out of the 7 models of dump trailers that we offer, 5 of them come standard with TELESCOPIC CYLINDERS instead of the traditional scissor lift hoist that you might have seen on most of our competitor’s dumps. We firmly believe that telescopic dump cylinders are the future of dump trailer design, and we are on the forefront of pushing that technology to the market. It’s not a new approach to dumping heavy loads by any means – it’s been used for decades by heavier duty semi-end dump trailers and heavy duty dump trucks.
Our heavy duty Telescopic Cylinder is a 3 stage cylinder that uses a KTI brand power-up, gravity-down system to help conserve energy. We also offer an optional Wireless Remote for additional convenience.
What are the benefits of telescopic cylinders?
- Provides greater lifting power than a traditional scissor lift hoist
- More front of body dumping leverage
- Handles imperfectly balanced loads more efficiently
- Less stress on overall frame of the trailer
- Ease of system maintenance due to front mount location
- Efficient, tried and true technology
Superior Powder Coating System
At Diamond C we place a huge importance on the coating that ships with your trailer. We’ve spared no effort or expense to ensure that each trailer comes with an extraordinary finish that is exceptionally durable and beautiful. We’ve partnered with Sherwin Williams to develop our very own custom DIFFERENCE MAKER POWDER COATING SYSTEM to produce extraordinary trailer finishes.
We use a 6 step process to ensure our custom trailer powder coating is the best coating option possible for your trailer. Watch below as Jacob takes you on a tour of the entire process from start to finish:
We offer 8 standard colors alongside 4 special colors that can be applied to any trailer. Want something custom or a unique color tailored specifically to you? No problem – check with your DEALER when you order.
