Trailer coupling: Rigid & detachable models, costs & tips

Trailer hitch – The sun is shining, you can hear children laughing and music is streaming from the speakers in the parks.
It’s summertime and everyone wants just one thing – to get out of the city and go on vacation!
It’s super easy with a folding caravan.
But there is one important little thing to consider when traveling with a trailer – the trailer coupling.
It ensures that the trailer drawbar is completely enclosed and still remains movable.
The ball socket encloses the ball head and prevents the trailer from detaching from the vehicle.
Here you can find out everything about the different models and what else you need to consider.
Finally, you will find the approximate costs you will incur.

Models: Fixed or detachable towbars?

Depending on the type of vehicle, there are various towbars that fulfill their purpose.
If you don’t have one, a roof tent may be an option for you.
For example, the most common towbar for cars is the ball head towbar, as it allows the trailer to be towed safely but flexibly.
The automatic pin coupling is then used for larger vehicles such as trucks or agricultural vehicles.
By swiveling the operating lever in the direction of the truck body, the coupling pin is lifted and locked in this position.
The coupling is connected after the trailer drawbar has been pushed into the coupling jaw and the pin falls through the eye with spring force assistance.
These are the different models of trailer couplings:

  • the pin coupling, (agriculture and forestry)
  • the ball head coupling (cars and older bicycle trailers)
    • Removable
    • Fixed/ Rigid
    • Pivotable
  • the jaw coupling (trucks and tractors)
  • the fifth wheel coupling (semitrailers)

D-value: What is it & what does it determine?

The D value is stamped on the type plate of a trailer coupling.
Its unit is kN.
The D-value can be calculated from the permissible total mass of the towing vehicle and the trailer.
The higher the D-value, the greater the mass that can be attached to a coupling.

Trailer coupling: What to consider?

There are a few details to consider both before and after the purchase.
For example, it is important to find out in advance what support and towing capacity your vehicle can withstand.
A Smart has a different capacity to an SUV.
In addition, you must not ignore the general road traffic regulations when retrofitting.
For example, the license plate must always be visible.
The same applies to rear-end collisions or misuse of the trailer, which must be checked immediately.
Exceeding the load or trying to uproot a tree with the trailer coupling can have fatal consequences.
The trailer coupling can break off completely and the towed load would move around uncontrollably on the road.

  1. Before buying: check vehicle type, drawbar load and trailer load
  2. License plate must not be covered (§ 27 of the StVo)
  3. Immediately to the workshop in the event of a rear-end collision (hairline cracks)
  4. Damage due to misuse (exceeding load = breakage)
  5. E-cars and hybrid vehicles not suitable for trailer couplings

When does a trailer coupling have to be registered?

A modern towbar is often registration-free and therefore does not necessarily have to be registered.
Exceptions are towbars without EU approval, where drivers must obtain a “partial certificate for retrofitted parts” from TÜV or DEKRA, which costs around 40 euros.

Costs: Price and installation of a trailer coupling

The cost of a detachable towbar with installation varies depending on the model and accessories.
In total, you should expect to pay between 500 and 1000 euros.
You may also need an adapter, a special lock to protect against theft and, depending on the situation, detachable bike racks.
This drives up the final price.
Nevertheless, this should be done professionally in a specialist workshop, as the vehicle has to be lifted and the installation is a complex task.
The price of a rigid towbar costs less, but is more suitable for drivers who make frequent use of trailers.

Offroad
Raised and extra stable for road and off-road… What do you do if you are traveling in regions with poor roads or drive an off-road vehicle or SUV whose dome height does not fit conventional trailers? The solution: the off-road tent trailer from CAMPWERK – specially developed for extreme conditions. This unique model impresses with a raised and particularly robust AL-KO chassis that can withstand even the most demanding off-road routes. The entire body is made of lightweight but sturdy aluminum, reinforced with durable stainless steel components. So you are perfectly equipped for any terrain.
Black / Silver
Available now: The CAMPWERK Offroader in the exclusive Black/Silver Edition CAMPWERK is expanding its range and now also offers the popular off-road tent trailer in the coveted Black/Silver Edition. The high-quality aluminium body is completely anodized in matt black, while the mudguards are powder-coated in elegant “Gun Silver Metal”. An absolute eye-catcher on any road and in any terrain!
The off-road trailer from CAMPWERK impresses with its lightweight construction: Thanks to the aluminum body, the base only weighs around 300 kg when empty. With a permissible total weight of 1.5 tons, it offers an impressive payload capacity of up to 1.2 tons – ideal for small excursions, transport and even larger expeditions.

Visually, the trailer blends in perfectly with the appearance of an off-road vehicle or SUV with its coarse-tread MT tires and robust, full-length aluminium mudguards. The mudguards are also designed in such a way that they are ideal for the safe transportation of petrol and water canisters or gas bottles.

To ensure flexibility, the off-roader’s tyres can be individually adapted to the towing vehicle on request, so that only one set of spare wheels is required. The standard ball head coupling can also be optionally replaced with a DIN or NATO eye.
T-drawbar or V-fork ?
Thousands of trailer drivers know the problem of tight spaces only too well: if you drive into a narrow lane and have to turn, it is important to back your car as far as possible against the trailer in order to get around the bend without any problems. With a T-drawbar, you can utilize the maximum steering angle. This is precisely why we at CAMPWERK rely on this tried-and-tested technology – for optimum flexibility and maneuverability, no matter how tight things get.

Material and processing.
The tent fabric of our trailer tents is made from a high-quality, 450 g blended fabric, also known as canvas. This unique combination of cotton and polyester combines the advantages of a natural fiber with those of a modern high-tech material. The result is a robust, breathable fabric that impresses with its pleasant feel and high dimensional stability.

The tent fabric, which is also used by the military, is impregnated and particularly tear-resistant thanks to the ripstop process. In this special weaving technique, thicker threads are woven into the fabric at intervals of around 10-15 millimetres, giving the fabric its characteristic tiled structure and exceptional tear resistance. It goes without saying that our fabrics are opaque and therefore offer optimum protection and privacy.
The basis of our trailer tents is a robust stainless steel frame with a thickness of 3×3 cm. A 1.8 cm thick, water-resistant wooden floor panel is securely fastened to this sturdy frame with stainless steel screws. The frame of the trailer tents is also made of galvanized steel tubing and special stainless steel components that ensure maximum stability. The modern surface finish not only offers a high level of corrosion protection, but also gives the material a pleasant feel and ensures a durable, weatherproof construction.
We rely exclusively on yarn from the German market leader Amann. Thanks to the combination of a cotton core and a high-tenacity polyester core, this yarn is characterized by a particularly high tensile strength and excellent water resistance.

On contact with water, the cotton coating swells and closes the seam holes created during sewing. For additional protection, all seams in the roof area are fitted with a transparent sealing strip to ensure maximum waterproofness.
Less is sometimes more.
We are often asked: What about the water column? For tent fabrics, the impermeability of the fabric is specified in the form of the water column. For cotton tents, this value is usually around 300 to 400 mm. However, our tent fabric offers an exceptionally high water column for cotton fabric of around 750 mm. This means that theoretically more than 75 cm of water can stand on the material before the first drops penetrate.

A major advantage of cotton as a natural raw material is its ability to swell when it gets damp, which provides additional waterproofing. In contrast, synthetic fabrics, which cannot swell, must have a much higher water column (between 3,000 and 10,000 mm, depending on the material) in order to achieve comparable waterproofness.

Premium mattress.
An excellent mattress is the basis for healthy and restful sleep. Just as every person is unique, their mattress should also be individually tailored to them.
Our premium mattress adapts perfectly to the contours of the body and promotes orthopaedically correct positioning of the spine. Thanks to targeted pressure relief, back muscles and intervertebral discs can relax optimally. The innovative construction and high-quality materials create an ideal sleeping environment.
There are no compromises at CAMPWERK: We rely on flexible visco foam with memory function. The unique combination of supportive foam core and relieving visco foam topper ensures maximum sleeping comfort.
Suspension.
Good ventilation is crucial for your well-being and sleep hygiene. To ensure maximum sleeping comfort, we combine our mattress with an innovative Froli slat base. The flexible spring elements form a comfortable slat base with individually adjustable firmness zones. This combination ensures orthopaedically correct positioning of the body and provides targeted, pressure-relieving support. This effectively prevents tension and one-sided strain. The open, air-permeable cells also enable optimum ventilation and create a healthy sleeping environment.
