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.
RGN trailers combine the lowest possible deck height with the convenience of drive-on loading. Key specifications:
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.
RGN trailers are the preferred choice for equipment that is too tall, too sensitive, or too heavy to load by other means:
The RGN’s drive-on capability is especially valuable at remote job sites where a crane or forklift is not available for loading.
Choose an RGN over other trailers when:
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.
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:
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.
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:
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.

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.
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.
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.
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.
