Highly recommend Opus camper Adelaide, we purchased an op15 , great hybrid and great value.
Love our new OP4 TLX camper.
Had a couple of small issues however Opus were excellent to deal with and quickly & efficiently addressed these.
About to head out for our 2nd trip and can't wait to experience the camper again.
Very quick response and good info
We just picked up our OPUS OP4 and had a fantastic handover experience with Glen. He was professional, friendly, and walked us through everything clearly, making sure we felt confident and ready to go. The OP4 looks amazing and we can’t wait to start our adventures. Great service and support – highly recommend!
Finally bit the bullet after going to 2 caravan shows in Melbourne and bought our family of 4 and opus op4 tlx. Glen and Adam were quite happy to answer any questions to help us make the decision. Hand over with glen at the keysborough hq was great, he explained everything to us. We love the ease of set up and pack down and can't wait to take it out for its 1st trip!
If you are on the fence about getting an opus, do it!
We purchased a band new Opus OP13 in February 25 - definitely the best hybrid pop-top caravan in the market! While there are way too many goodies to list, I can mention the electric lift roof, super-queen mattress, diesel heater, 4-burner slide-out kitchen, 2 freshwater tanks, 5 solar panels (500 W) and the roomy ensuite to name a few. The van is very well designed and built, and the independent spring suspension, electric brakes and DO35 off-road hitch makes it a dream to tow along. I can add much more descriptive text, but I strongly recommend you visit the factory in Keysborough and see for yourself - and especially have a chat with the "Opus guru" and Sales Executive Adam who had the time and patience to show us all the OP13 features and helped us to go for it! We have already camped in our OP13 and survived two very cold nights (around 1 degree C) in the middle of Tassie. Thanks Adam & Purple Line - we are very happy with our investment, and we certainly look forward with many more "glamping" expeditions. M&F (Blackmans Bay, Tasmania).
An amazing purchasing and hand over experience at Opus HQ in Keysborough. Jess and Glen were on the front foot with information, particularly with a minor delay in delivery due to Cyclone TC. Handover day was great fun, very comprehensive and even involved a towing lesson when Glen learned it was my first time towing. Can’t wait to get out on the road with the family and have some adventures.
Not a "review writing" person, but had to this time because of the top shelf service we received from Adam and the team at Opus, I am far from an expert on all things outdoors, no question was silly, everything was explained in a detailed handover, and then when I got the camper home and had forgotten 90% of what I was told, Adam answered the phone every time to walk me through what ever issue I thought there was (there wasn't, it was all operator error). Love the new rig and the family cant wait to get out in it. Highly recommend.

FAQs

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.
