What are RGN, Double Drop, Gooseneck and Lowboy Trailers?Posted On 14th August 2019
When it comes to truck loads, you have a lot of different trailer options.
There are RGN trailers used for shipping, single drop trailers, and double drop trailers, with each type going by several different names.
With so many choices it can be hard to know which one is best for your shipment.
To make sure you’re well informed on all the different types of trailers, we’ve put together this comprehensive guide. From removable goosenecks to double drop flatbeds, we’ve included all the information you need on each trailer type (also - learn about What is a Step Deck Truck).
What is an RGN Trailer
We hear a lot of people asking “What does RGN stand for?” or “What is RGN?” RGN stands for removable gooseneck trailer. They’re also often just referred to as gooseneck trailers.
RGN trailers are a type of flat deck trailer, allowing them to haul a wide range of large items that wouldn’t be able to fit into an enclosed space. In this sense, they’re similar to standard double drops and lowboys, however, there is one important difference. The gooseneck at the front can be removed, creating a ramp.
A lot of people ask us how to load a gooseneck trailer. Well, once the ramp has been created you can literally just drive your load right on to the trailer.
This makes loading heavy wheeled equipment on to goosenecks extremely easy compared to other trailer types.
Because of this, RGN trucks are a popular choice for a wide range of heavy equipment, including:
- Large trucks
- Pile Hammers
- Waste & Recycling Equipment
Essentially, if you’re looking for a trailer that will allow you to drive your equipment or heavy machinery up on to it, goosenecks are the way to go.
RGN trailers come in a number of different variations, including single drop and double drop. You can also have hot shot loads for a gooseneck. Hot shot loads are smaller loads pulled by medium duty or one-ton trucks.
What is a Single Drop Trailer
Single drop trailers drop down at the front then remain flat all the way to the end of the trailer. Because they drop down and are low to the ground they are great for carrying tall loads, giving them an advantage over standard flatbed trailers. However, they are not quite as low to the ground as double drop trailers.
Single drop trailers are designed to carry loads that are too long for a step deck and provide support at the rear without letting any of the load hang over the edge. They can also be fitted with a gooseneck, which only adds to their versatility.
What is a Double Drop Trailer or Lowboy
A double drop trailer, also known as a lowboy or a double drop lowboy, has two drops in deck height.
These trailers have a well in between the two axels that’s extremely low to the ground. The end of the trailer is slightly higher than the well but lower than the front, giving it two different levels. This allows for more flexibility when dealing with oversized loads.
Like single drops, double drop trailers can also have goosenecks as well. So, when you’re talking about RGNs vs lowboys, they’re often the same thing.
Double drop RGNs or lowboy RGNs have the advantage of a removable gooseneck, as well as a double drop deck to accommodate taller loads.
RGN double drop trailers are perfect for carrying:
- Construction equipment
- Large vehicles
- A wide range of tall oversized loads
Essentially, if you’re going to be transporting something and you’re worried about height, go with a double drop truck or an RGN lowboy, since drop deck trailer height can be up to 12 feet tall.
Trailer Dimensions: RGN, Single Drop, and Double Drop
Trailer and freight dimensions often vary widely. They come in a wide range of shapes and sizes, depending on the manufacturer as well as the intended use.
That being said, there are some standards in place for trailer sizes. The following information will give you an idea of the size of each trailer type.
When talking about RGN trailer dimensions, you need to remember that goosenecks can also be double drops and lowboys. So, RGN trailer specs can fluctuate quite a bit.
That being said, the typical RGN trailer can have a length anywhere from 20’ - 40’, a height of 18” - 5’, and a width generally around 8.5’.
Single Drop Trailer Dimensions
Drop deck trailer dimensions can vary depending on the trailer.
The average length of single drop trailers ranges from 35’ - 63’ feet, while the height is anywhere between 18” - 2’. Like RGN trailers, they’re usually about 8.5’ wide. They can carry loads up to 10’ high.
Double Drop Trailer Dimensions
Double drop deck semi trailer dimensions vary less than other trailers.
Their overall length is usually around 48’, with the upper deck between 6’ - 10’, and the lower deck usually about 30’.
As with other types of trailer, they’re generally around 8.5’ wide.
Double drop trailers can carry the tallest loads at up to 12’ high.
