Overview

The Kaufman Car Hauler is an open vehicle-transport trailer designed for moving multiple cars, pickup trucks, vans, and SUVs. The Double Deck EZ 4 is one of Kaufman’s primary commercial vehicle-transport configurations and can carry as many as four vehicles when their combined size and weight fit the trailer’s limits.

The trailer uses a double-deck arrangement to provide approximately 67 ft of total loading space within a trailer that has an approximately 47-foot main deck length. A hydraulically operated rear platform allows the operator to adjust the deck during loading and position vehicles on two levels.

The EZ 4 can be configured with a gooseneck ball coupler for heavy-duty pickup-truck operation or an SAE kingpin for connection to a commercial truck tractor. This makes the trailer useful for independent vehicle haulers, dealerships, auction transporters, and small commercial fleets.

Compared with a full-size high-mount automobile transporter, the Kaufman EZ 4 carries fewer vehicles but can be easier to operate, load, and maneuver.

Key Characteristics

The Kaufman EZ 4 combines a 31-foot upper deck with a lower deck measuring approximately 30 ft plus a 6-foot dovetail. This creates enough loading area for several combinations of passenger vehicles and light trucks.

A common load arrangement places a full-size SUV on the forward upper deck, a pickup or van on the rear lower deck, and two small or midsize cars through the center portion of the trailer.

The self-contained hydraulic system raises and lowers the rear deck platform. A wireless remote allows the operator to control the platform while monitoring vehicle and deck clearance.

Ridged expanded-metal runners provide tire traction in rain and other challenging conditions. Aluminum loading ramps bridge the transition between the ground and trailer deck.

Vehicle combinations must be planned according to actual length, height, ground clearance, wheelbase, and weight. The ability to physically fit four vehicles does not automatically mean that the load remains within the trailer’s payload or axle limits.

Common Specifications

Vehicle Capacity

The EZ 4 is designed to carry up to four vehicles.

Actual capacity depends on:

  • Vehicle length
  • Vehicle width
  • Vehicle height
  • Vehicle wheelbase
  • Vehicle ground clearance
  • Individual vehicle weight
  • Combined payload
  • Required spacing between vehicles

Deck Length

The main trailer deck measures approximately 47 ft.

The upper and lower deck arrangement provides approximately 67 ft of total vehicle-positioning space.

Upper Deck

The upper deck is approximately 31 ft long and includes a hydraulically lifted rear platform.

The platform can be positioned during loading to create access and clearance for vehicles carried on the lower deck.

Lower Deck

The lower section commonly provides approximately:

  • 30 ft of flat deck
  • 6 ft of dovetail

The dovetail creates a more gradual approach angle for loading low-clearance vehicles.

Frame Construction

The trailer uses a tubular steel frame.

Representative construction includes:

8-by-3-inch tubular-steel main frame

6-by-2-inch heavy-wall tubing in selected chassis areas

10-by-4-inch tubular-steel tongue on gooseneck versions

GVWR

A GVWR of approximately 25,000 lbs is common.

The actual available payload equals the GVWR minus the trailer’s empty weight and any permanently installed equipment.

Some representative trailers have an empty weight around 9,000 lbs and an available payload near 16,000 lbs, but the certification plate should be used for the specific trailer.

Axles

Three 8,000-lb axles are commonly installed.

Actual axle capacity does not override the trailer’s certified GVWR or applicable legal weight restrictions.

Suspension

Slipper-spring suspension is commonly used.

The suspension provides a straightforward mechanical design suitable for commercial vehicle-hauling service.

Brakes

Electric brakes are commonly installed on all wheels.

A breakaway system applies the trailer brakes if the trailer separates from the tow vehicle.

Tires

A common tire specification is 215/75R17.5 with a 16-ply rating.

A mounted spare tire may be included.

Coupling Options

Available coupling configurations include:

  • Adjustable 2 5/16-inch gooseneck ball coupler
  • SAE 2-inch kingpin
  • The selected coupling must match the tow vehicle and trailer rating.

Hydraulic System

The rear platform uses a self-contained hydraulic system operated by a wireless remote.

Hydraulic cylinders, hoses, fittings, controls, battery, and charging equipment require regular inspection.

Loading Ramps

Eight-foot aluminum ramps are commonly included.

The ramps must be positioned correctly and remain within their individual and combined capacity ratings.

Deck Surface

Ridged expanded-metal runners with an open center are commonly used.

A heavier mesh-floor option may be available to provide additional tie-down locations and support tire-based securement equipment.

Securement Equipment

Depending on the deck and ordered equipment, the trailer may use:

  • Wheel straps
  • Tire ratchets
  • Transport chains
  • Wheel loops
  • Deck-mounted tie-down points
  • Winch equipment

Landing Gear

Two heavy-duty drop-foot jacks support the trailer when it is disconnected.

Representative configurations use dual 12,000-lb jacks.

Lighting and Wiring

DOT-approved wiring, connectors, LED lighting, reflectors, and required identification lights are commonly installed.

Specifications should be confirmed through Kaufman Trailers before ordering because equipment and ratings can change.

  • Low-clearance vehicles may require careful ramp positioning
  • Heavy pickups and SUVs can reduce the number of vehicles carried
  • Load placement significantly affects tongue or kingpin weight
  • The trailer may require a commercial truck and CDL depending on its configuration and use
  • Commercial auto transport requires specialized insurance and operating authority
  • Each vehicle must be secured independently

Driver and Operator Considerations

The operator should develop a loading plan before moving the first vehicle onto the trailer. Vehicle length, weight, height, ground clearance, and final delivery order should all be considered.

Heavy vehicles should be positioned to maintain safe weight on the tow vehicle and trailer axles. Excessive forward weight can overload the tow vehicle, while insufficient forward weight can create unstable handling.

Upper-deck vehicles must have enough clearance from vehicles positioned beneath them. The driver should check body panels, roofs, mirrors, antennas, spoilers, and suspension movement.

Hydraulic platforms should never be moved while a person is standing beneath or between moving deck components.

After loading, each vehicle should be placed in park or gear, have its parking brake applied when appropriate, and be independently secured using approved equipment.

Maintenance and Ownership Notes

The steel frame should be inspected for cracks, corrosion, bent components, damaged welds, and evidence of overloading.

Expanded-metal runners and deck connections should be examined for broken welds, distortion, sharp edges, and excessive wear.

Hydraulic cylinders, hoses, fittings, valves, battery connections, and controls should be checked for leaks and damage.

Loading ramps should remain straight and should have undamaged connection points and traction surfaces.

Wheel straps, ratchets, chains, hooks, and tie-down anchors require regular inspection. Equipment with cuts, deformation, corrosion, or damaged hardware should be removed from service.

Axles, slipper springs, equalizers, hangers, wheel bearings, electric brakes, tires, lights, and the trailer’s electrical system require routine maintenance.

Buying Considerations

  • Confirm the exact model and year
  • Verify the GVWR
  • Check the trailer’s empty weight
  • Calculate the available payload
  • Confirm the number and rating of the axles
  • Inspect the tubular-steel frame
  • Check all deck welds and expanded-metal runners

Comparison to Similar Trailers

Compared with a full-size high-mount car carrier, the Kaufman EZ 4 carries fewer vehicles but is generally easier to maneuver and may require less specialized loading experience.

Compared with a three-car wedge trailer, the EZ 4 provides an additional vehicle position and a hydraulically adjustable deck. The hydraulic system also adds weight, cost, and maintenance requirements.

Compared with an enclosed car hauler, the Kaufman open carrier provides greater vehicle capacity and easier loading access. An enclosed trailer provides better protection for high-value, collectible, and exotic vehicles.

Compared with a flatbed trailer, the Kaufman model provides vehicle-specific decks, ramps, and securement equipment. A flatbed is more versatile for general freight but is less efficient for routine multi-vehicle transport.

Comparable commercial vehicle transporters include the Cottrell Car Hauler Trailer and Sun Country Car Hauler Trailer.

Regulatory and Compliance Notes

The Kaufman Car Hauler must comply with federal, state, and local requirements governing trailer dimensions, GVWR, brakes, lighting, tires, vehicle securement, and commercial operations.

A combination with a GVWR or gross combination weight rating above certain thresholds may require a commercial driver’s license. Requirements depend on the tow vehicle, trailer rating, operation, and jurisdiction.

For-hire interstate vehicle transportation may require operating authority, insurance filings, vehicle markings, registration, and compliance with Federal Motor Carrier Safety Administration regulations.

Each transported vehicle must be independently secured with equipment that has adequate working load limits. The securement method must prevent forward, rearward, lateral, and vertical movement.

Overall loaded height must be measured whenever vehicles are positioned on the upper deck. The driver must also verify total length, width, axle weights, and tow-vehicle ratings.

Real World Operating Notes

In practical operation, the Kaufman EZ 4 provides a middle ground between a basic two- or three-car trailer and a full-size commercial automobile transporter.

A load of four compact or midsize cars may fit efficiently. A combination containing large pickups, vans, or SUVs may reduce practical capacity to two or three vehicles.

Loading order matters. Vehicles scheduled for the first delivery should remain accessible whenever possible, but safe weight distribution takes priority over delivery convenience.

The hydraulic platform and wireless remote allow the operator to monitor clearances while adjusting the deck. Final clearances should be checked after the platform is locked into its transport position.
