RGN Trailer Transport: Removable Gooseneck Specs & Capacity Guide

The RGN (Removable Gooseneck) trailer is the most versatile tool in heavy equipment transport. Its defining feature — a front gooseneck that detaches and lowers to ground level — allows equipment to be driven directly onto the trailer without ramps, rigging, or cranes. For tall machinery that can’t be tilted and must be loaded level, the RGN is often the only practical solution. Freedom Heavy Haul operates RGN trailers in all 48 contiguous states.

Specifications & Dimensions

RGN trailers combine the lowest possible deck height with the convenience of drive-on loading. Key specifications:

  • Deck height: 8–20 inches (varies; lowest of any trailer type when neck is detached)
  • Deck length: 24–53 feet standard; stretch RGN models extend to 65+ feet
  • Standard width: 8.5 feet; oversized configurations available with permit
  • Capacity: 42,000–80,000 lbs standard; multi-axle and flip-axle configurations to 150,000+ lbs
  • Legal load height: Up to 11’6″+ depending on deck height and state limits
  • Gooseneck detach: Hydraulic or mechanical; lowers front to ground for drive-on access

The “flip axle” configuration adds a retractable rear axle that deploys for heavy loads, increasing weight rating without adding permanent trailer length. Many RGN trailers also feature hydraulic suspension for load leveling on uneven surfaces.

What Equipment Can Be Transported?

RGN trailers are the preferred choice for equipment that is too tall, too sensitive, or too heavy to load by other means:

  • Telescoping boom cranes: Height when boomed up requires lowest possible deck
  • Reach stackers and container handlers: Tall mast height; drive-on loading critical
  • Large excavators: When height + lowboy deck still exceeds limits
  • Agricultural equipment: Wide-span harvesters, sprayers with booms folded
  • Industrial machinery: Large presses, CNC machines, manufacturing equipment
  • Transformers and generators: When height or weight requires maximum clearance
  • Military and government equipment: Specialty vehicles with non-standard dimensions

The RGN’s drive-on capability is especially valuable at remote job sites where a crane or forklift is not available for loading.

When to Choose This Trailer vs. Other Options

Choose an RGN over other trailers when:

  • Equipment must be driven on — no crane or forklift available at origin or destination
  • Load height on a lowboy would still exceed legal limits — RGN’s extra-low deck (8-18 inches) provides maximum clearance
  • Equipment is extremely sensitive to tilting (loaded electronics, precision instruments, liquid-filled systems)
  • Weight is in the 42,000–80,000+ lbs range with tall dimensions

RGNs are generally more expensive than lowboys due to the hydraulic gooseneck mechanism and more complex setup. When a standard lowboy can accommodate the load, it may be the more cost-effective choice.

Permits & Regulations

RGN loads almost always require oversize permits, as the equipment being transported typically exceeds standard dimension or weight limits. The permit process for RGN loads is the same as other oversize moves:

  • Permits required from every state the load travels through
  • Pilot cars required for loads over 12 feet wide (front) and over 14 feet wide (front + rear)
  • Law enforcement escort may be required for loads over 16 feet wide
  • Night-only travel sometimes required for extremely wide loads in urban areas

Freedom Heavy Haul’s permit team handles all paperwork and coordinates with state DOTs on your behalf. Turnaround for standard permits is 24–72 hours; superloads require 2–4 weeks.

Transport Rates & Cost Factors

RGN transport costs are typically 10–20% higher than equivalent lowboy moves due to the additional setup time for gooseneck detachment and reattachment, hydraulic system maintenance, and generally higher trailer depreciation costs. Key cost factors:

  • Distance and number of states (permit costs per state)
  • Load dimensions and weight
  • Number of pilot cars required
  • Origin/destination accessibility (remote sites, limited turning radius)
  • Seasonal demand and fuel surcharges

Typical ranges: $1,000–$3,500 for regional moves; $2,500–$8,000+ for long-haul moves with multiple permits. Call (866) 305-6018 for a free, accurate quote.

Frequently Asked Questions

What does RGN stand for in trucking?

RGN stands for Removable Gooseneck. It refers to the detachable front section of the trailer that connects to the truck’s fifth wheel. When removed, the front of the trailer deck rests on the ground, creating a ramp for equipment to drive directly onto the trailer without the need for cranes or additional loading equipment.

What is the difference between an RGN and a lowboy trailer?

Both are low-deck trailers, but the key difference is in the loading method. An RGN has a gooseneck that detaches to allow drive-on loading — the front lowers to the ground. A standard lowboy has a fixed or non-removable gooseneck and requires ramps or a crane to load equipment. RGNs are preferred when equipment must be driven on or when maximum deck height clearance is needed.

How much weight can an RGN trailer haul?

Standard 3-axle RGN trailers handle 42,000–48,000 lbs. Adding a flip axle or a 4th axle raises capacity to 60,000–80,000 lbs. Multi-axle RGN platforms can handle 150,000+ lbs. For extreme superloads, modular hydraulic platforms with dozens of axles can move 500+ tons.

How is an RGN loaded?

Loading an RGN involves: (1) positioning the trailer at the load site, (2) hydraulically or mechanically detaching the gooseneck and lowering the front deck to the ground, (3) driving equipment up the ramp/deck, (4) reattaching the gooseneck and securing the load with chains and binders. The process typically takes 30–90 minutes depending on load complexity.
