Concept of an off-road trailer for mountain rescue services designed to carry specialist rescue equipment from the base to the action point.



Project based on the needs of GOPR services (Voluntary Mountain Rescue Organization ) during cave rescue actions, but the trailer can be used in various kinds of actions.

So far, an extra necessary equipment, for each action, has been packed loose in a simple chest-shaped trailer unadapted to difficult conditions and off-road terrain. The need to design a dedicated trailer was determined by the GOPR management (Grupa Jurajska). The new trailer chassis was made to be pulled behind an off-road vehicle in mountainous terrain and to cope with tough obstacles. The upper body was designed to maximally facilitate the access to the equipment regardless of the weather conditions. My project was elaborated to meet the needs of the rescue services and to improve the course of the action. The rescue equipment deployed functionally in the space of the module ready to be transported, shorten the rescuer reaction time considerably.

We are supposed to write something about this trailer here...

Upper Body Features

You probably noticed what we fight for in our body concept. It’s drop-down sides that give you easy access to your equipment and working tops all around your trailer.

We just prefer to keep our stuff in the right height so we don’t need to bend down too much!



Steel constructed coffer makes the body durable and resistant to corrosion and temperature. The chest is sealed tight with replaceable rubber gaskets, which keep interior dry!



Easy to unassemble, waterproof drop-down sides go with different finish material. Choose fitting option from our offer.



Interior is made from waterproof plywood with stainless steel connectors. Dividers’ perforation works well with QuickFist’s attach system.

Feel free to replace and reconfigure your sections dividers and equipment arrangement.



Steel Roof Carrier is equipped with handles and perforation to let you attach bicycles, kayaks and whatever you need.

It’s also designed to fit a roof tent. We use 120x160cm Autohome Overland Medium.



Whole interior is enlighten with LED lights controlled with the Power Panel.

Why not illuminate the chassis as well? Go with Tokyo Drift style a little and let your trailer shine!



1. opening boards - comfortable work tops on each side

2. maneuvering handles - maneuvering the trailer after unfastening

3. division into sections - fitting interior option to the concept of the vehicle user

4. screw connections - secured against unscrewing

Camping. Utility Features

Most important feature of D1 is setting up the camp.

Kitchen Section

In 2014 on the Hungarian border traffic we couldn’t have a better opportunity to fold out the kitchen worktop, play music and prepare coffee for us and the cars around.


Kitchen section gives you 150cm worktop to feel free space while preparing any food or drinks.

90cm kitchen shelf with rubber attachments to keep the dishes, cutlery, cutting board, bottles, boxes and other stuff at your fingertips.

Place for a double torch gas stove with gas installation underneath the shelves.

Easy access to a fridge on a sliding supports.

On demand, we will install sink with a tap.

Tools Section
We will need an axe! …and a shovel!


Quick access to the tools is a must!
Why not to have them all in the sight?

Customize your Tools Section to your needs. Fishing equipment? Hunting riffles? Tripod with a cooking pot? Yes! Let’s fit them there too!

And this face of security guards every time we open this side for border control. :D

Inventory Section


120x70x50cm space for bigger stuff you don’t want to worry about with access from the front and from the kitchen side.

We keep here the fridge on the sliding supports, but when we decide to take the fridge to the car we exchange it for a storage boxes.

Electrical installation keeps the fridge connected to the power.

Bottled water, additional tents and bags can go there as well.

Baggage Section
…the last but not least.


Two sliding drawers for loose equipment like shoes, clothes, cooking pots and paper towel.

Large shelf for camping table and 4 folding chairs with a belt attachment.

Power Control Panel to control battery status, lights inside and outside the trailer and couple power plugs.

Small storage space at your service. We like to fit there small extinguisher and a camping flashlight.
