ATC builds all-aluminum enclosed trailers across several product lines, each designed for specific hauling applications:

ATC Car Trailers (ROM 400/450 Series)

These standard-duty enclosed car haulers are a good fit for transporting cars, motorcycles, and similar vehicles. With units available from 16 to 28 feet in length, they are built for buyers who need enclosed protection in a simpler configuration.

Heavy-Duty Car Haulers (ROM 500/550 Series)

These higher GVWR builds (up to 13,200 lbs) are built for heavier vehicles and higher payload demands than standard-duty car trailers. They are used for race cars, larger vehicles, or other equipment that require more capacity and a heavier-duty setup. 

Gooseneck Trailers (ROM 700/750G Series)

For buyers who need a longer trailer and a different towing configuration, ATC also offers gooseneck models. These extended-length builds range from 36 to 48 feet and are commonly used for multi-vehicle hauling, commercial transport, or other jobs where added capacity is a priority. 

Stacker Trailers (ROM 750S Series)

ATC stacker trailers use an integrated 14 or 16-foot tiltable lift system to transport two vehicles in a single enclosed trailer. Their two-car stacker configurations, ranging from 24 to 30 feet, are useful when you need to maximize vehicle capacity without moving into a larger transport setup. 

ATC Snowmobile Trailer Configurations

These trailers are designed for snowmobile hauling, with layouts that support drive-in/drive-out loading. Features such as front and rear ramp access and interior protection components help accommodate winter transport needs. 

Custom and Specialty Configurations

ATC also offers trailers with custom layouts and specialty features for more specific applications. Depending on the build, options can include living quarters, added storage, or equipment packages tailored to how you plan to use the trailer. 

Key Features and Benefits of ATC Enclosed Trailers

Every ATC aluminum trailer shares a core set of construction features that separate it from steel-frame competitors:

• All-Aluminum Frame: ATC uses fully welded aluminum construction, which helps reduce overall trailer weight and avoids the rust concerns that come with steel frames. 
• Lower Tow Weight: With weights 10% to 15% lighter than equivalent steel trailers, ATC enclosed trailers can help you balance cargo capacity with your tow vehicle’s limits. 
• LifeTrac Wall System: This modular interior track system lets you add or reposition cabinets, tie-downs, and other accessories with less permanent modification. 
• Dexter Torsion Axles: These axles are designed to support a smoother ride and stable handling during transport.  
• Clean Exterior Construction: Many models include a one-piece aluminum roof and streamlined exterior panel design. 
• Warranty Coverage: ATC offers limited warranty coverage for structural, workmanship, and electrical components. 

Typical Specs and Options

At Millennium Trailers, you can compare several core specifications to find the ATC enclosed trailer for sale that fits your hauling needs. 

• Length and Trailer Type: ATC offers bumper pull and gooseneck models in multiple lengths, from compact enclosed trailers to larger builds designed for heavier or multi-vehicle hauling. 
• Body Width and Interior Height: Many ATC trailers are built with an 8.5-foot body width, and some models offer additional interior height for greater clearance. 
• GVWR and Axle Configuration: Depending on the model, ATC trailers can range from 7,700 lbs to 25,200 lbs GVWR. Tandem-axle configurations are common across much of the lineup, while some larger or heavier-duty builds use triple axles for added capacity. 
• Ramp Doors and Flooring: Some ATC models include a 4,000-lb rear ramp door with a 7.5-foot opening width and a full transition flap. Flooring options may include extruded aluminum, black coin composite, or woven vinyl mat surfaces, depending on the configuration. 
• Electrical and Power Options: ATC trailers may include 30A or 50A breaker boxes, all-LED interior and exterior lighting, 12V USB ports, and available upgrades such as a 100Ah lithium battery or solar trickle charger. 
• Climate Control: Some builds can be equipped with 13,500 or 15,000-BTU A/C units, along with a heat strip or heat pump.
• Specialty and Living Quarters Features: Certain configurations also offer stacker lift systems or living quarters, including sleeping areas, plumbing fixtures, and basic kitchen components. 

How To Choose the Right ATC Car Trailer

ATC’s ROM series offers a clear progression from standard to heavy-duty builds. Here’s how to match your requirements to the right tier:

1. Determine What You Plan To Haul

Standard enclosed car trailers in the ROM 400/450 Series may be enough for many cars and lighter cargo. Heavier vehicles, race cars, or equipment may call for the added capacity of the ROM 500/550 Series. 

2. Compare Bumper Pull and Gooseneck Configurations

Bumper pull models are often a practical choice for shorter lengths and more straightforward towing setups. On the other hand, longer gooseneck trailers are often better suited to heavier loads or multi-vehicle transport. 

3. Consider Stacker Capability

Transporting two vehicles in a single trailer requires the ROM 750S with its integrated tiltable lift system.

4. Review the Interior Layout and Equipment You Need 

ATC’s LifeTrac system allows for a more flexible interior. However, it still helps to decide early on what storage, tie-downs, cabinets, or work surfaces you want included. 

5. Plan for Travel Beyond the Haul Itself 

For longer trips, races, or multi-day events, consider trailers with added amenities, such as a kitchenette, bathroom, or sleeping area. 

Who ATC Trailers Are Built For

ATC trailers can be a good fit for racers, car enthusiasts, collectors, restorers, and powersports owners who want an enclosed aluminum trailer for protected transport. Our lineup also includes options for professional motorsport teams that need larger gooseneck or stacker models, as well as commercial buyers comparing trailer weight, cargo capacity, and overall configuration. 

These trailers also appeal to buyers who prefer to invest in a trailer that lasts for years and want to compare aluminum construction with other trailer types before making a decision.
