6’10” × 24′ Car Hauler / Equipment Trailer Plans – 14,000–16,000 lb GVWR

Product Overview

Build your own 6’10” × 24′ Car Hauler / Equipment Trailer with these professionally engineered trailer plans. Designed for either a 14,000 lb or 16,000 lb Gross Vehicle Weight Rating (GVWR), this heavy-duty tandem-axle trailer features a welded steel I-beam frame that delivers exceptional strength while maintaining a low deck height for easier loading. It’s ideal for hauling cars, trucks, Jeeps, UTVs, tractors, skid steers, compact construction equipment, and a wide variety of other heavy loads.

The trailer features a nominal 6’10” × 24′ deck with an actual deck length of approximately 24′ 3½”, an overall width of 102″ at the fenders, and an overall length of approximately 29′ 5″ including the tongue. The plans include complete engineering information for building either the 14,000 lb or 16,000 lb configuration, depending on the materials and components selected during construction.

Multiple engineered configuration options are included throughout the plans, including deck styles, removable or fixed fenders, loading ramps, tie-down anchor locations, front rail options, winch mounting, toolbox and tongue tray options, tongue jack configurations, rear supports, and more, allowing you to configure the trailer to match your hauling needs. The 14,000 lb configuration is designed around 7,000 lb straight or 4″ drop axles, while the 16,000 lb configuration utilizes 8,000 lb straight axles.

Heavy-Duty I-Beam Construction

The trailer is built around a heavy-duty welded steel I-beam frame engineered to provide exceptional strength, rigidity, and long-term durability for demanding hauling applications. Structural I-beams are combined with welded C-channel, angle, and other steel components to create a durable fixed-deck trailer capable of supporting either a 14,000 lb or 16,000 lb Gross Vehicle Weight Rating (GVWR), depending on the configuration you choose to build.

The 14,000 lb configuration is designed around 7,000 lb straight or 4″ drop leaf-spring axles, while the 16,000 lb configuration utilizes 8,000 lb straight leaf-spring axles. The heavy-duty frame provides outstanding stability and durability for hauling cars, trucks, Jeeps, UTVs, tractors, skid steers, compact construction equipment, and a wide variety of heavy loads.

Proper fabrication, welding, material selection, component installation, and load placement remain essential to the safety, durability, and long-term performance of the completed trailer.

Loading Ramps & Fender Options

The plans include multiple steel loading ramp configurations, allowing you to select the ramp length, width, material, and load capacity that best fits your application. Hidden slide-under ramp storage is included to keep the ramps securely stored beneath the trailer deck while maintaining a clean, professional appearance. Builders may also choose longer ramps with alternate storage arrangements when a reduced loading angle is desired.

The plans are designed around removable steel fenders, providing additional clearance when loading wider vehicles or equipment. Builders may also choose to permanently weld or bolt the fenders in place if removability is not required. Rear support options are also included to help stabilize the trailer during loading and unloading.

Professionally Engineered Plans

These trailer plans were professionally engineered by Synthesis Engineering Services. The engineering package evaluates structural members, frame geometry, suspension placement, connection points, and load paths to provide a strong, durable trailer design.

As with any trailer project, proper material selection, fabrication quality, welding, assembly, maintenance, loading practices, and compliance with applicable laws remain the responsibility of the builder.

Understanding Trailer Weight, GVWR, and Payload

These plans allow you to build a trailer with either a 14,000 lb or 16,000 lb Gross Vehicle Weight Rating (GVWR), depending on the configuration you choose. GVWR represents the maximum allowable weight of the completed trailer and everything loaded on it, including cargo, equipment, accessories, and the trailer itself.

The base 14,000 lb trailer weighs approximately 2,200+ lbs before decking and optional equipment. A typical completed 14K trailer with common options weighs approximately 3,000 lbs, although final trailer weight will vary depending on your material selection, decking, ramps, tie-down options, toolbox, winch, battery, tongue accessories, jack configuration, wheels, tires, axles, and other builder-selected options.

Available payload can be estimated using the following formula:

GVWR − Actual Completed Trailer Weight = Available Payload

For the most accurate payload calculation, weigh the completed trailer on a certified vehicle scale after construction. Always stay within the ratings of the completed trailer, axles, suspension, tires, wheels, coupler, hitch, and all other installed components.
