FAQs: Light Weight Camper Trailers
What is the lightest off-road camper trailer in Australia?
The OPUS OP4 ST is our lightest camper trailer with superb off-road capabilities. It minimises weight innovatively, using state-of-the-art materials and concepts like Air Beam technology. You won’t notice the difference until you feel how nimble and manoeuvrable it is on uneven terrain.
How much can you pack into a lightweight camper trailer?
The amount of gear and supplies you can pack into lightweight camper trailers depends on their payload, which can vary significantly.
- The OPUS OP4 ST has a payload of roughly 590 kg, an outstanding number compared to other lightweight camper trailers in Australia.
General packing tips:
- Prioritise the essentials—Gather everything you’d like to take along on your trip, be ruthless in determining what you will need, and abandon the rest. Remember that you will pass stores and other places to replenish supplies along the way, so focus on items you cannot replace or purchase when the need arises.
- Distribute added weight evenly—Avoid unbalancing your lightweight camper trailer, as this can cause it to sway.
- Carry lightweight gear—Choose lightweight camping gear and supplies over weightier versions if possible. Although the OPUS OP4 ST can carry significant weight, the amount soon builds up if you don’t focus on finding the lightest versions of each item.
- Make efficient use of available storage—Group items logically to make them accessible when required but be prepared to fill voids with other items that fit rather than leaving empty spaces.
Can a lightweight camper trailer go off-road?
Not all lightweight camper trailers in Australia are suitable for off-road adventures, but they are not a problem for the amazing OPUS OP4 ST. Its light, nimble design and bespoke off-road features make it the dream trailer for more adventurous trips to Australia’s most rugged, inaccessible locations.
