Complete Guide to RGN, Gooseneck, Single & Double Drop Trailers

Table of Contents

When you’re in the freight trucking business, choosing the right trailer can make or break your operation. We’ve all been there – standing in front of different trailer options, wondering which one will handle our cargo best. Different trailers are designed for specific cargo sizes, weights, and loading challenges. Today, let’s walk through five popular trailer types that every heavy hauler should know: Gooseneck, RGN (Removable Gooseneck), Single Drop, Double Drop, and Lowboy trailers. Getting familiar with these options will help you optimize your semi truck mpg and tractor trailer mileage while keeping your cargo safe and sound.

What is a Gooseneck and RGN Trailer?

You might be wondering “what does RGN stand for in trucking?” Well, “RGN” stands for removable gooseneck trailer, and it’s one of the most versatile pieces of equipment you’ll find on the road. The beauty of an RGN trailer lies in its clever design – that front gooseneck can actually be removed to create a ramp that goes right from the ground to the trailer bed.

Picture this: instead of struggling with cranes or forklifts, you can simply drive your heavy machinery straight onto the trailer. It’s like having a built-in loading dock wherever you need it. This is exactly why RGN trucks have become so popular among contractors and heavy equipment operators.

So what is RGN trailer used for? These workhorses are perfect for transporting large construction equipment – think cranes, excavators, dozers, and loaders. They’re also great for agricultural machinery like tractors and combine harvesters. Basically, if it’s got wheels and weighs a ton (literally), an RGN truck can probably handle it.

Most RGN trailers feature a flat deck with a lowered middle section – what we call a drop deck. This design gives you that extra clearance you need to haul tall cargo without hitting height limits on the road. A typical RGN trailer measures around 29 feet in length for the main deck, stays within about 8.5 feet wide, and can handle weight capacities exceeding 150,000 pounds depending on how many axles you’ve got. The combination of that detachable gooseneck and the drop deck design is what makes RGN trailers such a game-changer in heavy haul trucking.

What is a Single Drop Trailer?

A single drop trailer (step deck trailer)takes a different approach – it features a lowered front section with the rear deck staying flat. Think of it as a compromise between a standard flatbed and the more specialized options. This lowered front deck lets you carry taller items than you could with regular flatbeds, while still maintaining good stability and ground clearance.

The nice thing about single drop trailers is that many come with an optional gooseneck attachment. This adds flexibility by making hitching easier and improving weight distribution across your rig. These trailers work great for loads that need some height reduction but don’t require the extreme low deck that you’d get with an RGN or double drop setup. It’s all about finding that sweet spot between trailer height and your tractor trailer mileage.

What is a Double Drop Trailer ?

Now we’re talking about the heavy hitters – double drop trailers. These bad boys have two deck drops: one right after the gooseneck and another just before the rear axles. The result? An incredibly low central deck that can sit just 18 inches off the ground.

Why would you want something so low? When you’re dealing with oversized or heavy equipment that simply won’t fit on higher trailers due to height restrictions, that low deck becomes your best friend. A double drop trailer gives you three distinct levels: the front deck above the gooseneck, that super-low middle section (we call it the well), and the rear deck.

Among common trailer types, these handle the tallest cargo you can imagine – specialized equipment like tanks, massive bulldozers, and drilling rigs. Many double drop trailers also feature a removable gooseneck, just like RGN trailers, so you get that same front-loading convenience.

This is why double drop trucks and RGN lowboy setups are so popular in construction, mining, and heavy equipment transport. They can handle very wide or long items while keeping you within road-legal height limits, which helps optimize your tractor trailer mileage too.

Trailer Dimensions and Specifications Comparison

Trailer Type	Deck Height (inches)	Typical Length (ft)	Width (ft)	Max Weight Capacity (lbs)	Key Features
RGN Trailer	18 – 30 (varies by model)	~29 – 53	About 8.5	55,000 to 150,000+	Removable gooseneck, drop deck, ramp loading
Single Drop Trailer	Moderate drop in front deck	40 – 53	About 8.5	Up to ~48,000	Lowered front deck, optional gooseneck attachment
Double Drop/Lowboy	Extremely low central deck	40 – 53	About 8.5	Up to ~48,000	Two deck drops, removable gooseneck, ideal for very tall cargo

The RGN trailer gives you one of the lowest bed heights available, plus that convenient ramp loading feature. Single drop trailers offer a decent height reduction for taller cargo that isn’t too extreme. Double drop trailers are your go-to when you absolutely need the lowest deck height possible.

Conclusion: Choosing the Right Trailer Type

At the end of the day, picking the right trailer comes down to understanding your cargo’s dimensions, height requirements, and how you need to load it. Whats an RGN trailer good for? It’s excellent for very tall, heavy, or oversized equipment that benefits from easy ramp loading and flexible deck sizing. Single drop trailers work well when you need moderate height clearance without going to extremes. Double drop or lowboy trailers are your answer for the tallest and heaviest machinery that demands extremely low decks.

Using the right trailer isn’t just about getting the job done – it helps maximize your semi truck mpg and tractor trailer mileage by optimizing weight distribution and cargo dimensions. That’s where LUEN’s services come in handy, streamlining trailer selection and transport quoting to help you find the perfect trailer for any freight job.
