Double Drop RGN Trailers

A double drop removable gooseneck (RGN) trailer is a type of flat deck trailer characterized by its long, narrow gooseneck trailer hitch. The term “double drop” refers to dual low points in the deck between the axles of the trailer.

The front of a double drop trailer is engineered to be higher than the back of the trailer, providing better legal height clearance up to 12 feet on the lower deck. Double drop trailers are useful for transporting particularly large loads that cannot fit in enclosed trailers.

Differences Between RGN, Double Drop, Gooseneck, and Lowboy Trailers

Although all double drop style trailers exhibit the same distinctive low points, they come in four slightly different models for use with particular load and application types. 

Removable Gooseneck (RGN) Trailer

RGN trailers are distinguished by the removable gooseneck trailer hitch, which operates under hydraulic or mechanical means to create a ramp onto the lower deck. The benefit of the ramp is that vehicles can be rolled or driven onto the trailer. Coupled with the flat deck design, the RGN trailer is particularly useful for moving large construction equipment which can be wheeled onto the trailer without assistance from a crane or other lift. 

Double Drop Trailer

Double drop trailers are characterized by the distinctive double dip in the deck between the axles. Although they are similar in construction to RGN trailers, double drop trailers do not have the removable hitch and must therefore be loaded using overhead cranes, forklifts, or other loading equipment. Double drop trailers do not exhibit the same weight capacity as RGNs, although additional axles can be added to improve this capacity.

Gooseneck Trailer

Gooseneck trailers, as the name implies, exhibit the distinctive gooseneck trailer hitch. Unlike the RGN, the hitch on a standard gooseneck trailer is not removable, so it does not have the same useful ramp option. A gooseneck hitch offers numerous benefits over a standard fifth-wheel trailer hitch. Gooseneck ball hitches are capable of towing heavier loads than a fifth-wheel. In addition, the attachment of a gooseneck takes up significantly less space on the trailer, allowing for more space on the deck.

Lowboy Trailer

Lowboy trailers are similar to double drop trailers, and the terms are often used interchangeably. The primary characteristic of a lowboy trailer is the exceptionally low drop in the deck. The lower height makes it easier to carry particularly tall loads within legal height limits. Lowboys can be equipped with both removable and standard gooseneck hitches for ease of loading.

Learning Double Drop Basics

When choosing the best double drop trailer for your needs, it is important to have a thorough understanding of the towing regulations in the states through which you will be traveling, including the trailer’s empty weight, the load weight, and the overall weight of the trailer and load combined. Heavy haul loads will typically have different requirements, so knowledge of each state’s weight limits and requirements is critical.
