Criterion Trailers: Features, Sizes, Uses, and Buying Guide

Choosing an enclosed cargo trailer is easier when you begin with a clear idea of what you need to haul, how often you plan to travel, and how much space your equipment requires. A trailer used by a contractor every day has different demands than one used for weekend recreation or occasional household moves. Construction quality, axle capacity, doors, interior height, flooring, tie-down points, and available options all play an important role. For Montana buyers, weather and road conditions can also make durability and practical design especially important.

A good enclosed trailer does more than keep cargo in one place. It protects tools, equipment, motorcycles, recreational gear, merchandise, and supplies from rain, snow, road debris, and unwanted attention. It can also serve as organized mobile storage for a business. Instead of unloading everything after every trip, many owners can keep frequently used items secured inside the trailer. This makes an enclosed cargo trailer useful for construction crews, landscapers, mobile service businesses, motorsports enthusiasts, campers, homeowners, and anyone who needs dependable hauling space.

For buyers comparing Criterion trailers, one of the main advantages is the range of enclosed cargo configurations available for different hauling needs. Criterion manufactures cargo trailers in multiple widths, and Montana Trailer Sales carries models ranging from compact single-axle units to larger tandem-axle trailers. Current Montana Trailer Sales listings have included sizes such as 6 x 10, 6 x 12, 8 x 16, 8 x 18, and 8 x 20 feet, giving buyers options for both lighter cargo and larger equipment.

Construction Features That Matter

Trailer construction deserves close attention because the frame, exterior, roof, floor, walls, and running gear all affect long-term performance. Criterion states that its trailers are built in Caldwell, Idaho, with heavy-duty frames, reinforced construction methods, high-grade components, and premium aluminum composite siding on applicable models. Its standard cargo specifications also list features such as LED lighting, radial tires, a one-piece aluminum roof, water-resistant OSB flooring, sidewall airflow vents, and a stone guard. Exact specifications can vary by size and configuration, so buyers should always review the details of the specific trailer they are considering.

Choosing the Right Trailer Size

Size should be based on more than what fits your cargo today. Think about what you may need to carry six months or several years from now. A 6-foot-wide trailer can be practical for tools, household items, lawn equipment, or a smaller business setup. Larger 7-foot and 8-foot-wide models can offer more room for motorcycles, ATVs, construction materials, larger equipment, or organized workstations. Interior height is also important. Some Montana Trailer Sales Criterion inventory has offered 78-inch or 84-inch interior heights, which can make loading and moving around inside much more comfortable.

The axle setup is another major buying decision. A single-axle trailer can work well for lighter loads and buyers who prefer a smaller, easier-to-manage unit. Tandem axles are commonly considered when more cargo capacity, a larger trailer body, or frequent hauling is required. For example, Montana Trailer Sales has listed Criterion models with 3.5K single axles, 3.5K tandem axles, and 5.2K tandem axles depending on the trailer. Larger tandem models may also include electric brakes. The correct tow vehicle, hitch rating, cargo weight, and trailer ratings should always be checked before towing.

Doors, Cargo Access, and Interior Layout

Door design can have a big effect on everyday convenience. A rear ramp door is useful when loading motorcycles, wheeled equipment, carts, or other items that are difficult to lift. A side RV-style door provides quick access when you do not need to open the rear of the trailer. Several Criterion models sold through Montana Trailer Sales combine a rear ramp with a 32-inch side RV door. Buyers should also think about where equipment will sit inside the trailer and whether the door placement will remain accessible after the trailer is fully loaded.

Customization can turn a basic cargo trailer into a trailer designed around a specific job or hobby. Criterion lists options that include rear double doors, ramp doors, side doors, windows, stabilizing jacks, D-ring tie-downs, interior wall finishes, lighting, 110V outlets, charging centers, powered exhaust fans, heaters, air conditioning, and convertible sleeping or storage systems. Not every option is appropriate or available for every model, but knowing what can be added helps buyers plan a trailer that will remain useful as their needs change.

Common Uses for Enclosed Criterion Trailers

Contractors can use an enclosed trailer to organize power tools, ladders, fasteners, generators, and job-site supplies. Landscapers may need secure space for smaller machines and equipment. Powersports owners can transport motorcycles or recreational equipment while protecting them from weather and road debris. Small businesses can create mobile inventory, service, or delivery setups. Homeowners may simply want a secure trailer for moving furniture, storing seasonal equipment, or handling renovation projects. The best trailer is not always the largest one. It is the model that gives you enough capacity without creating unnecessary towing weight or unused space.

Before buying, create a simple checklist. Measure the largest item you expect to load, estimate the combined cargo weight, and confirm the towing capacity of your vehicle. Then consider the required interior height, axle configuration, brake setup, rear door style, side access, tie-down locations, lighting, flooring, and storage needs. Buyers should also think about where the trailer will be parked and whether the overall length and width will fit comfortably. A few measurements before the purchase can prevent expensive changes later.

Compare the Trailer, Not Just the Price

While researching trailers online, buyers may come across searches for 3d trailer sales along with local trailer dealers, manufacturers, and different enclosed cargo brands. Whatever dealer or listing you are comparing, focus on actual specifications rather than choosing from price alone. Look at axle ratings, construction, dimensions, wall and floor materials, door configuration, warranty details, available upgrades, and dealer support. Two trailers that appear similar in photos can be very different once you compare their construction and equipment. A detailed comparison usually gives a much clearer picture of long-term value.

Working with a knowledgeable local dealer can also simplify the buying process. Montana Trailer Sales carries Criterion enclosed cargo trailers and provides both available inventory and options for buyers planning specific configurations. Its Criterion inventory has included compact single-axle models as well as larger tandem-axle units with features such as ramp doors, side doors, recessed D-rings, higher interior ceilings, Polycore siding, spare tire setups, and other equipment depending on the model. Many listed Criterion units also include a three-year warranty, although buyers should confirm current warranty coverage for the exact trailer before purchase.

Protecting Your Trailer After Purchase

Regular care can help any cargo trailer provide better service over time. Inspect tires before trips and maintain the correct tire pressure. Check wheel hardware, lights, electrical connections, hitch components, safety chains, doors, hinges, ramp hardware, brakes, and tie-down points on a routine basis. Keep the interior dry and clean, especially after hauling equipment covered in mud, snow, or moisture. Owners should also follow manufacturer maintenance instructions and address unusual tire wear, braking problems, damaged seals, or electrical issues early rather than waiting for a small problem to become a larger repair.

Finding the Right Criterion Trailer in Montana

The right trailer should make hauling safer, easier, and more organized. Criterion offers enclosed cargo configurations suitable for many commercial, recreational, and personal uses, while available options allow buyers to select features that fit the way they actually work or travel. Start with cargo size and weight, choose the proper axle and towing setup, and then consider doors, interior height, tie-downs, electrical features, and other upgrades. Montana Trailer Sales can help buyers compare available Criterion models and select a trailer based on practical needs instead of guesswork.
