Which Mud Dog Pressure Washer Trailer is Best For You?

November 5, 2025

Choosing the right pressure washer trailer is crucial for contractors and business owners in the pressure washing industry. Whether you handle residential driveways or large-scale industrial projects, Mud Dog Trailers offers a diverse lineup of pressure washer trailers designed to meet a variety of needs.

From the compact Mud Puppy to the dual-system Beast , we will give a detailed breakdown for each of our trailers including pricing, features, and ideal case-scenarios so you know which pressure washer trailer will best suit your needs.

The Mud Puppy

The Mud Puppy is Mud Dog’s most compact and affordable trailer unit, priced at $14,995.

Built on a single-axle 5×10 frame, it packs the same great “Mud Dog” components into a smaller trailer.

Every Mud Puppy comes with a Honda GX630 engine and Beckett burner hot-water system, delivering 6 GPM at 3,500 PSI for effective cleaning power. It carries a 225-gallon water tank which is plenty for residential jobs or small commercial tasks.

With one high-pressure hose reel and a 35-gallon chemical tank, the Mud Puppy is ideal for solo operators or new businesses focused on houses, driveways, and other light-duty projects. Its compact single-axle design makes it easy to tow and maneuver in tight residential areas. (If you’re unsure how much water capacity you need, see our blog Water Tank Sizing 101 .)

The Mud Dog Trailer

The Mud Dog Trailer (standard model) is the flagship trailer rig, engineered for versatility and durability. Priced at $18,995, this tandem-axle trailer is a self-contained hot-water pressure washing system built to “clean anything, anywhere, anytime”.

Like the Mud Puppy, it features a Honda engine, General Pump, and Beckett burner, but with a larger 525-gallon water tank for extended runtime. The Mud Dog Trailer blasts 6 GPM at 3,500 PSI and is set up as a two-gun unit, meaning two operators can work simultaneously for improved efficiency.

Dual high-pressure hose reels (with 100 ft hoses) come standard, along with a toolbox and a chemical injection system. This model’s tandem 6×12 heavy-duty trailer (7,000 lb GVW) can handle heavier loads and rough daily use.

The Mud Dog Trailer is a great all-around choice for commercial pressure washing businesses and can tackle everything from retail storefronts and fleets to concrete cleaning. Contractors who do a mix of residential and light-to-medium commercial jobs will appreciate this unit’s balance of power and capacity.

8 GPM Super Mud Dog

For those who need extra cleaning power, the 8GPM Super Mud Dog Trailer offers an upgraded performance on the same robust frame. Starting at $19,995, the Super Mud Dog is described as “the same as the original Mud Dog Trailer, just bigger and badder,” featuring a larger Honda GX690 (24 HP) engine and a high-flow pump pushing 8 GPM at 3,500 PSI.

This boost in flow means you can clean large surfaces faster and support two operators at high output which is perfect for busy commercial crews or jobs that demand speed.

The Super Mud Dog shares the Mud Dog Trailer’s heavy-duty 6×12 tandem-axle build and 525-gallon tank, so you get the same sturdy platform with more punch under the hood.

Choose this model if your business often handles large parking lots, warehouses, or other jobs where higher GPM can significantly cut down cleaning time. The modest price jump for the Super Mud Dog delivers a “monster cleaning system” geared toward efficient two-gun operation.

It’s a smart investment for growing businesses that require extra capacity without moving to the top-tier models.

Bulletproof Mud Dog

Stepping up in both features and durability, the Bulletproof Mud Dog is built to thrive in the harshest environments. This model is priced at $27,995 and earns its name with a super heavy-duty 7×14 tandem-axle (10,000 lb) trailer frame and premium components.

The Bulletproof Mud Dog is powered by a Honda GX690 24 HP engine and delivers 8 GPM at 3,500 PSI of hot water cleaning force which is the same output as the Super Mud Dog, but with additional upgrades.

It includes a 525-gallon water tank and two 35-gallon chemical tanks, allowing you to carry multiple chemicals or a larger supply for long jobs.

Uniquely, this model comes factory-equipped with an air-powered soft wash system (with manifold and dedicated hose reel) for low-pressure chemical application. That means in addition to standard high-pressure blasting, you can do roof cleaning, siding soft washing, or sanitizer application using the same trailer.

Other rugged features include an industrial spray-lined trailer bed, “Liger” alloy wheels, and dual Summit hose reels with non-marking hot water hoses.

In short, the Bulletproof Mud Dog is ideal for heavy commercial use – think cleaning large commercial buildings, parking garages, heavy equipment, or doing varied jobs (from gum removal to gentle roof washing) all with one rig. It’s designed for contractors who demand reliability and versatility day in and day out.

Diesel Dog

The Diesel Dog offers a powerful alternative for those who prefer diesel engines. Priced at $27,995, it features a long-lasting Kohler/Kubota diesel engine and a diesel-fired burner, so the entire system runs on diesel fuel.

This trailer is built on the same stout 7×14 dual-axle platform (with 5,200 lb axles) as the Bulletproof, including a 525-gallon water tank and heavy-duty 10,000 lb GVW trailer construction.

The Diesel Dog’s pump outputs approximately 7 GPM at up to 4,000 PSI – delivering slightly higher pressure, which can be advantageous for stripping stubborn grime.

With dual hose reels and the capacity for two-gun operation, it’s well suited for industrial and continuous-duty use, such as cleaning heavy machinery, factories, or large concrete areas. Diesel engines are known for fuel efficiency and longevity during long runtimes, making this model a smart choice if your crew tackles all-day jobs or if you want the convenience of a single fuel type for both engine and burner.

The Diesel Dog doesn’t include the integrated soft-wash system of the Bulletproof, but it can be equipped with downstream chemical injectors for applying detergents.

Choose the Diesel Dog if you need a reliable workhorse for heavy-duty, long-duration projects – for example, municipal cleaning contracts or industrial facilities maintenance. Its diesel powertrain offers excellent durability and better fuel economy over extended use.

The Beast

True to its name, The Beast is an extreme-capacity trailer built for the most demanding pressure washing operations. With a price tag of $54,995, The Beast is essentially two complete hot-water pressure washers on one trailer.

It houses twin Honda GX690 engines (MAGNUM series) powering two pumps, each rated at 8 GPM, 3,500 PSI, so you can run two high-output spray guns simultaneously without sacrificing performance.

This monster rig carries over 1,000 gallons of water (two 525-gal tanks) and is mounted on a beefy 20-foot dual-axle trailer (14,000 lb GVW) to handle the weight. Just ensure you have a capable tow vehicle, and remember that hauling 1000+ gallons of water calls for careful attention to trailer weight and braking (dual axles with electric brakes are standard on this unit).

The Beast comes fully loaded with accessories: two hot-water burners, four 100′ high-pressure hoses, three wands, a gas-powered soft wash system with remote manifold, and even two Whisper Wash surface cleaners mounted on board. It also features auxiliary LED light bars for nighttime work.

The Beast is best for large-scale and industrial jobs where you need maximum throughput – for example, cleaning stadiums, airports, multi-story building exteriors, or running multiple crews from one unit.

Find Your Ideal Pressure Washing Trailer

Mud Dog Trailers has a model for every level of pressure washing business – from the entry-level Mud Puppy for residential jobs to the top-tier Beast for industrial-scale projects.

As you compare these models, consider your typical job size, frequency, and whether you need extras like dual-gun operation or built-in soft wash capabilities. For a balanced mix of power and portability, many small businesses start with the Mud Dog Trailer (standard) or upgrade to the Super Mud Dog for higher flow.

If your work involves heavy commercial cleaning or you want all-in-one flexibility, the Bulletproof Mud Dog (with added soft wash system) is a compelling choice. For those who prioritize fuel efficiency and long-term value in intensive use, the Diesel Dog provides diesel power and endurance. And if no job is too big and you’re scaling up crews, The Beast will ensure you’re never underpowered on the job.
