Bruder EXP-4

The Bruder EXP-4 makes camping adventures easy, very easy. No set-up, no pack-up, and instantly level. The smaller brother of the Bruder EXP-6.

The Bruder EXP-4 soaks up bumps, undulations, and corrugations like no other off-road trailer. The Bruder suspension truly revolutionizes off-road travel and camping; not only can the EXP-4 level out uneven terrain for camping, but it can also counteract steep side slopes while off-roading. For perfect towing balance, the suspension can also calibrate its ride height to suit a wide range of tow vehicles.

The Bruder EXP-4 is fully engineered: the suspension, the chassis, and even the body construction. We use best practice design and engineering principles, regularly overlooked by others in the trailer industry. This includes correct geometry throughout the full range of suspension motion, thereby maximizing the efficiency of components including all four Bruder-specific remote canister monotube shock absorbers.

The EXP-4 has nearly triple the adjustable wheel travel of the nearest air suspension system. Our suspension is only available on Bruder expedition trailers and is made from Australian 450 grade high tensile circular hollow section steel and shaped to maximize ground clearance. Our attention to detail and knowledge of off-road environments makes the EXP-4 extremely durable and in maximum height mode, its body can achieve over 850mm of clearance.

Offroading with the Bruder EXP-4

The EXP-4 incorporates the same technology and design practices we supply commercially to global exploration companies, military groups, and humanitarian organizations. We understand how demanding the off-road environment can be so the EXP-4 has been tested for durability in 50 Celsius (122 Fahrenheit) ambient heat and incorporates manual override and backup systems to get you through an unlikely worst-case scenario. Although lightweight, the EXP-4 has 2600 kg rated axles, ventilated disc brakes for maximum stopping power and can accommodate tyres up to 37 inches tall.

The EXP-4 chassis is also completely unique. It is airtight and completely sealed, with no openings for salt, sand or other debris to get caught within it (just like large ships or steel poles that hold up a seaside jetty are sealed). Plus the EXP-4 undercarriage has rear recovery points and an optional Warn recovery winch. The chassis joins forces with the fully engineered EXP-4 body cell, which is made from lightweight composite material up to 60 mm thick - engineered to handle up to 10 times its own weight.

Steep inclines are nothing for the Bruder EXP-4

Optimizing insulation is key. The EXP-4 body cell has an insulation R-value over 5.1 making it not only the strongest but also the most insulated trailer in its class. Even the main drinking water supplies and all plumbing are kept within the EXP-4 body cell, not outside mounted to the chassis. This means precious water supplies are better protected from damage off-road and prevent freezing in extreme climates.

The EXP-4 body uses a closed-cell epoxy-bonded composite, which is better insulated and has 20 percent more tensile strength than commonly used polyester bonds. Unlike so many “composite” trailers that use aluminum foam sandwich panels or honeycomb core panels, our material and construction methods are both stronger and more insulated. Our composite construction improves insulation by preventing pathways for heat or ice to migrate to the interior. 

Escape in instant comfort
Inside the EXP-4 is first-class comfort. Sleep in bliss even if it is snowing, raining, or storming. With a hugely spacious 6 ft wide and 7 ft2 long sleeping area, the EXP-4 is supremely comfortable. The interior can be tailored to accommodate young children on a 1.8m bed that doesn’t impact the use of the main sleeping area. No setup, no pack up - the EXP-4 bed is always ready and level regardless of the terrain.

With an insulation R-value over 5.1, you’re better protected from heat or cold, plus climate control air-conditioning or interior heating can be added. The EXP-4 can be fully closed with blinds shut for those who like to sleep in absolute darkness, or the windows can be opened with pull-down insect mesh allowing you to enjoy tremendous views, with protection. Or relax with both doors completely open. It’s your choice on how you’d like to experience nature.

Careful consideration in the design allows for a huge sense of space as well as creature comforts. Internal USB charging outlets and LED lights are conveniently located, along with three huge storage shelves and even dedicated hanging space for clothing.

Comfort is key in the Bruder EXP-4

The Bruder EXP-4 makes it easy to travel and explore your favorite destinations in supreme comfort and security. Entry and exit are made easy for the tall or short, with up to 12 inches of adjustment. Rest easy with the added protection and safety of knowing you have the strongest engineered composite body all around you. The EXP-4 can also be slept in discreetly when fully closed, giving outsiders no clue that you may be within it. In environments with dangerous animals, or just for a roadside stop, the ability to sleep locked safely within can be of great security to many travelers.

The EXP-4 sleeping area can accommodate two adults and three young children. For larger families, the EXP-4 roof is engineered to accommodate virtually any roof-top tent on the market.

Not all campers have a built-in outdoor barbeque like the Bruder EXP-4
