Inside the OP4

Built around the way you actually camp.

OP4 feature: A bedroom at each end

A bedroom at each end

Two inner-spring double beds, one at each end of the camper. Convert either into a king when you've got the space to spread out. A real window to wake up to.

OP4 feature: Lounge, eat, hang out

Lounge, eat, hang out

Inside or outside, the club lounge seats the whole crew around a real table. Card nights with mountains out the window, lunch in the shade on the long days.

OP4 feature: Built tough, set up easy

Built tough, set up easy

Galvanised chassis, off-road coupling, twin-shock independent suspension, paired with the same one-button Air Beam Technology as the smaller OPUS rigs. Set up in under five minutes.

OP4 feature: All-weather basecamp

All-weather basecamp

Diesel heating, reverse-cycle option, full ensuite. Stars overhead, fire out front. The trip doesn't end because the weather turned.

Common questions

Everything you want to know.

Under five minutes, and one person can do it solo. Pull up, level, hit the inflate button, peg out the annexe. The Air Beam tent inflates in three minutes. Door zips and the kitchen slide are the rest of it.

Yes. Galvanised chassis, off-road Cruisemaster DO35 hitch, coil-spring suspension with dual shocks, and 390 mm of ground clearance on mud-terrain tyres. Built to handle the corrugations and back tracks our owners take it down.

Triple-layer Air Beams pressurised to 7 psi, the same kind of technology used in US military rapid-deployment shelters. No poles to bend, snap or lose. We've tested it in every condition Australian camping throws at it. The wind doesn't faze it.

Comfortably. Two inner-spring double beds, one at each end, both convert to kings if you want the space. The convertible lounge sleeps two more. That's six off the rig itself. Add the inflatable annexe and you can fit four more, ideal when the cousins or grandparents come along.

200 Ah lithium handles up to a week off the grid for an active family, real-world depends on how you use it, how hot it is, and what you're running. The 2,000 W Renogy inverter drives 240 V appliances directly. 140 L of water gets a family several days before refill. Spec extra batteries to take total capacity up to 400 Ah if you want more off-grid confidence. Diesel heating, hot water and reverse-cycle are available as options.

Tow-away pricing covers everything except the optional accessories you tick at order. Solar, hot water, heating and reverse-cycle are popular picks. Build & Price your OP4 in the configurator to see your full price.
