Diamond C gooseneck trailers are among the best-engineered heavy-haul trailers on the Texas market. Built in Mount Pleasant, TX, Diamond C has become the go-to brand for contractors, ranchers, oilfield workers, and equipment dealers who need to haul serious loads — legally, safely, and reliably. Trailer Place in Wharton, TX stocks a wide selection of Diamond C gooseneck trailers and can order specific configurations.

Why Choose Diamond C for Your Gooseneck Trailer?

Diamond C is a Texas brand — built for Texas roads, Texas heat, and Texas loads. The company has been manufacturing trailers in Mount Pleasant since 1985 and is known for continuous engineering investment. Every Diamond C gooseneck trailer features:

  • MAX Ramps system — heavier, wider ramps than competitors at most price points
  • ENGINEERED BEAM technology — variable-thickness frame cross members at stress points
  • RockSolid Powder Coat finish (standard on most models)
  • Dexter electric brake axles
  • Sealed LED lighting throughout
  • GN coupler rated to load GVWR — no weak-link ball couplers on heavy models

Diamond C Gooseneck Trailer Models

FMAX212 — Gooseneck Flatbed (14,000 lb GVWR)

The FMAX212 is Diamond C’s entry-level gooseneck flatbed — a 20–25 ft trailer with 14,000 lb GVWR, 2-axle tandem, and a 102″ wide deck. It features a 5-inch channel main frame, 16-inch crossmembers, and a rear beavertail. Ideal for hauling skid steers, tractors, ATVs, hay, lumber, and general cargo. Pairs with a 1/2-ton to 3/4-ton truck equipped with a gooseneck ball.

LPD — Low Profile Dump Gooseneck (14,000 lb GVWR)

The LPD is Diamond C’s best-selling gooseneck dump trailer. Available in 12–16 ft bed lengths with 14,000 lb GVWR. The low-profile design lowers the center of gravity for stability when dumping. Pyramid-style floor reinforcement and 7-gauge steel floors handle the abuse of construction debris, rock, dirt, and gravel. See our full Diamond C dump trailers page for more dump-specific details.

HPGT — Heavy-Duty Pipe Top Gooseneck (21,000–25,900 lb GVWR)

The HPGT is Diamond C’s heavy-haul gooseneck platform — designed for contractors who need maximum payload capacity. Available in 20–40 ft lengths, GVWR up to 25,900 lbs with triple-axle configuration. The 8-inch I-beam main frame and ENGINEERED BEAM reinforcement handle heavy construction equipment, oilfield pipe, precast panels, and loaded hay stacks. Requires a 1-ton dually (Ford F-350/F-450, Ram 3500/4500, Chevy 3500HD DRW).

CAR HAULER Gooseneck (14,000–21,000 lb GVWR)

Diamond C’s gooseneck car hauler variants are designed for auto dealers, car flippers, and motorsports teams moving multiple vehicles at once. The GN car hauler configuration features a 102″ wide deck, low deck angle, MAX Ramp system, and winch provisions. GVWR options from 14,000 to 21,000 lbs cover 2- to 3-car loads. See our Diamond C car hauler page for more detail.

Towing Requirements for Gooseneck Trailers

Gooseneck trailers require a fifth-wheel style ball mounted in the bed of a pickup truck — not a standard bumper-pull hitch. The gooseneck design places the trailer’s tongue weight over the truck’s rear axle, allowing significantly higher GVWR ratings than bumper-pull equivalents. Most Diamond C gooseneck trailers require at minimum a 3/4-ton truck; the heavier HPGT and triple-axle models require a 1-ton dually. See our gooseneck trailer guide and best trucks for gooseneck towing in Texas for more information.

Pricing Context

Diamond C gooseneck trailer pricing starts around $9,000–$12,000 for the FMAX212 tandem axle and ranges to $25,000+ for fully-configured HPGT triple-axle units. Dump goosenecks run $10,000–$18,000 depending on size and capacity. Diamond C’s premium engineering commands a price premium over budget brands — but the durability, warranty support, and resale value justify the investment for serious working buyers.
