Best Rooftop Tent Annexes Australia 2026 — Add-On Rooms for Your RTT

There are a number of excellent RTT annex brands on the Australian market and we’ve only scratched the surface here — covering every brand and model available simply isn’t possible in a single post. If there’s a brand or model you’d like us to review, or if you want a head-to-head comparison between two specific annexes, shoot us a message through our contact page and we’ll put together a full review and send it directly to you.

If you’ve already got a rooftop tent, an annex is the single best upgrade you can make to your campsite. It transforms your setup from just a sleeping spot into a full outdoor living area — a sheltered space to change, store gear, keep the kids out of the rain, or even sleep an extra person or two.

But not every annex fits every tent, and the quality varies significantly between brands. In this guide we cover the best RTT annexes available in Australia right now, matched to the tents in our Best Rooftop Tents Australia 2026 guide, so you can find the right add-on room for your exact setup.

Quick Comparison Table

Why Bother With an RTT Annex?

A lot of people buy a rooftop tent and think the job is done. Then they spend a rainy night with nowhere to sit, no privacy to change, and their gear spread across the back of the ute getting wet — and that’s when they wish they’d bought an annex from the start.

Here’s what a good annex adds to your setup:

Extra living space. The area under your RTT becomes an enclosed room. That’s a huge deal on longer trips, especially with kids or when the weather turns.

Privacy. Getting changed in the open is fine until it isn’t. An annex with insect mesh doors and zippered privacy panels means you’ve always got a sheltered, private space.

Gear storage. Instead of leaving boots, chairs, and wet gear outside, everything goes in the annex. Keeps your sleeping area clean and dry.

Extra sleeping space. Most annexes have a removable PVC floor which means you can throw a stretcher or sleeping mat in there for an extra person. Great for families with kids.

Bug protection. Insect mesh doorways on quality annexes mean you can leave the sides open for airflow without inviting every mosquito and march fly in Australia to join you.

The only downside? You need to measure your vehicle’s roof height carefully before buying — annex drop sizes are not one-size-fits-all. More on that in the buying guide below.

The Best RTT Annexes in Australia 2026

1. Darche Hi-View/Panorama 1400 Annex — Best Overall

Price: ~$350–$450 | Fits: Darche Hi-View 1400 & Panorama 2 1400

If you’re running one of the Darche 1400 series tents — the Hi-View or the Panorama 2 — this is your annex. It’s purpose-built to attach directly to the base of these tents via a sail track and chunky zip, and the fit is seamless.

Built from tough 210D ripstop polyester oxford, it’s the same quality construction you’d expect from Darche — designed to hold up in the harsh Australian environment. The 550gsm PVC bucket floor is removable, which means you can take it out for a bare ground surface or leave it in for a clean, dry floor.

Three entries plus a rear vehicle access door means you’re never trapped or having to step outside to get to your rig. Each doorway has dual-zippered privacy panels and superfine insect mesh — essential for Australian camping where the bugs don’t ask for permission.

Available in 1.6m, 1.8m, and 2.1m drop heights, so you can match it to your vehicle setup. The 2.1m drop is ideal for lifted 4WDs and utes with raised roof racks — perfect for those of you running a Ram 2500 or Landcruiser with an aftermarket lift.

What we love:

• Perfect fit for Darche Hi-View and Panorama 1400 tents
• 210D ripstop polyester — tough and weather resistant
• 550gsm removable PVC bucket floor
• 3 entries plus rear vehicle access
• Superfine insect mesh doorways
• Available in three drop heights
• Privacy doors convert to awnings with optional poles

What to consider:

• Telescopic poles sold separately if you want to convert doors to awnings
• Measure your vehicle height carefully before selecting a drop size

Best for: Anyone running a Darche Hi-View 1400 or Panorama 2 1400 who wants the best matched annex for their setup.

2. Darche Hi-View 2200 Annex — Best for Families

Price: ~$400–$500 | Fits: Darche Hi-View 2200

If you’re running the larger Hi-View 2200 — Darche’s family-size tent that sleeps up to four — this is the matching annex. It’s the same quality construction as the 1400 annex but scaled up to suit the wider 2200mm tent footprint, giving you even more enclosed space below.

For families with kids, this combo is hard to beat. The tent sleeps the adults up top, and the annex becomes the kids’ zone — a stretcher or sleeping mat on the PVC floor, insect mesh keeping the bugs out, and privacy doors keeping everything contained. It’s essentially a two-room camping setup.

Available in 1.6m and 1.8m drop heights. If you’re on a standard height 4WD, the 1.8m gives you full standing room inside.

What we love:

• Matched perfectly to the Hi-View 2200 tent
• Extra wide footprint — more enclosed floor space than the 1400 annex
• Great for families with kids sleeping in the annex
• Same quality 210D ripstop build as all Darche annexes
• Removable PVC floor

What to consider:

• Only available in 1.6m and 1.8m drop — no 2.1m option
• Larger and heavier than the 1400 annex

Best for: Families running the Darche Hi-View 2200 who need a full two-room camping setup.

3. 23Zero Dakota 1400 Annex — Best for Comfort Campers

Price: ~$400–$500 | Fits: 23Zero Dakota 1400

23Zero’s annex for the Dakota 1400 follows the same design philosophy as their tents — built for comfort and usability, with a focus on keeping you dry and bug-free. It slides into the sail track on the base of the Dakota 1400 and zips up in minutes.

The polycotton construction breathes better than straight polyester, which reduces condensation on cool mornings — a nice touch. The PVC bucket floor keeps everything off the ground and zips out easily if you want a more open setup.

Like the Darche annexes, doors can be converted to awnings for extra shade with optional pole kits. Multiple entry points and insect mesh throughout mean you can get good airflow even with everything closed up.

What we love:

• Perfect fit for the 23Zero Dakota 1400
• Polycotton construction breathes well — less condensation
• PVC bucket floor — removable
• Multiple entry points with insect mesh
• Quality 23Zero build matching their tent range

What to consider:

• Check 23Zero’s website for current drop size availability
• Poles for awning conversion sold separately

Best for: 23Zero Dakota 1400 owners who want a matched, quality annex from the same brand.

4. iKamper Annex Plus — Best Premium Annex

Price: ~$700–$900 AUD (check current dealer pricing) | Fits: iKamper Skycamp 3.0, X-Cover 2.0

The iKamper Annex Plus is in a different league to everything else on this list — and the price reflects that. It’s a fully freestanding design, which means it stays standing even if you need to move your vehicle. That’s a genuinely useful feature most annexes don’t offer.

It’s much larger than a typical annex — iKamper describes it as several times the size of most competitors’ models — and the five-sided door design gives you an incredible sense of openness when the weather is good. Waterproof ripstop fabric with quality zippers handles the elements, and the modular accessory system lets you add an inner tent, canopy poles, or footprint depending on your needs.

Zips directly onto the entrance of compatible iKamper RTTs, and installation takes around 10–15 minutes without tools. At 12kg it’s light for what it is.

Available through iKamper’s Australian dealers — check ROOZE in Melbourne or other authorised dealers for current AUD pricing.

What we love:

• Freestanding design — stays up when you move the vehicle
• Much larger than standard annexes
• Five-sided door design — exceptional airflow and openness
• Modular — add inner tent, footprint, or canopy poles
• Waterproof ripstop fabric
• Zips directly onto compatible iKamper RTTs

What to consider:

• Premium price — most expensive annex on this list
• Only fits iKamper Skycamp 3.0 and X-Cover 2.0 series
• Check Australian dealer availability and current AUD pricing

Best for: iKamper Skycamp 3.0 owners who want the ultimate annex setup and aren’t afraid to pay for it.

5. Adventure Kings RTT Annex — Best Budget Annex

Price: ~$199 | Fits: Adventure Kings RTT

If you’re running the Adventure Kings RTT on a budget, their matched annex is the obvious choice. At around $199 it’s exceptional value and gives you all the basics — enclosed shelter, insect mesh, a PVC floor, and privacy panels.

Build quality isn’t in the same league as Darche or 23Zero, but for occasional weekend camping it does the job. The polyester construction handles typical Aussie conditions fine, and the PVC floor keeps things dry and clean underfoot.

Available through 4WD Supacentre. If you’re running the Adventure Kings RTT and want to add a room without spending another $400–$500, this is a solid, no-fuss option.

What we love:

• Very affordable at around $199
• Matched specifically to the Adventure Kings RTT
• PVC floor included
• Insect mesh doorways
• Available through 4WD Supacentre

What to consider:

• Build quality not as refined as Darche or 23Zero
• Polyester construction less breathable than polycotton
• Better suited to occasional camping than heavy year-round use

Best for: Adventure Kings RTT owners who want to add an annex without a big additional spend.

Buying Guide — How to Choose the Right RTT Annex

Step 1 — Match to your tent

This is the most important step. RTT annexes are not universal. They attach via a sail track and zip system that’s specific to each tent brand and size. Always buy the annex designed for your exact tent model. Mixing brands rarely works and can result in gaps, poor weatherproofing, and a setup that looks a mess.

Step 2 — Measure your drop height

Every vehicle sits at a different height, and annexes come in different drop sizes — typically 1.6m, 1.8m, and 2.1m. To find the right size:

1. Set up your RTT on your vehicle on flat, level ground
2. Measure from the underside of the open tent down to the ground
3. Choose an annex drop size within about 10cm of that measurement

As a general guide:

• 1.6m drop — lower vehicles, truck bed mounts, standard SUVs without a lift
• 1.8m drop — standard 4WDs and wagons
• 2.1m drop — lifted 4WDs, utes with raised roof racks, larger wagons

If you’re running a lifted Ram 2500, Landcruiser 79 Series, or similar, the 2.1m is almost certainly what you need.

Step 3 — Floor type

Most quality annexes come with a removable PVC bucket floor. This is worth having — it keeps the floor dry, stops mud and dirt tracking through, and gives you a clean surface to walk on. Some cheaper annexes have a sewn-in floor which can’t be removed for drying.

Step 4 — Entry points

Look for at least two entries — ideally three plus a rear vehicle access door. Three entries means you’re never walking around the outside of your setup to get somewhere, and the rear vehicle access is essential so you can get to your ute tray or wagon tailgate without stepping out into the rain.

Step 5 — Awning conversion

Some annexes allow the privacy doors to be converted into awnings using telescopic poles (usually sold separately). This is a great feature for hot days — you can open the walls up for shade and airflow without fully exposing the interior. Check whether this feature is available on the annex you’re considering and factor in the extra cost of poles if needed.

Frequently Asked Questions

Do I need an annex for my rooftop tent? You don’t need one, but once you’ve used one you’ll wonder how you camped without it. They’re especially valuable on longer trips, in wet weather, and for families.

Are RTT annexes waterproof? Quality annexes from Darche, 23Zero, and iKamper are fully waterproof when set up correctly. Cheaper polyester annexes may let in water at the seams in heavy rain. Look for taped or sealed seams if waterproofing is a priority.

Can I sleep in a rooftop tent annex? Yes. Most annexes with a removable floor are large enough for a stretcher bed or sleeping mat. They’re not as weather-tight or comfortable as sleeping in the RTT itself, but they work well as overflow sleeping for kids or extra guests.

How do I attach an RTT annex? Most annexes attach via a sail track running along the base of the RTT, with a chunky zip sealing the connection. The process takes 5–10 minutes once you’ve done it a couple of times. Always follow the manufacturer’s instructions for your specific tent/annex combination.

Can I leave the annex up if I move my vehicle? Standard annexes attach to the base of your RTT and will come down with the tent if you drive away. The iKamper Annex Plus is the exception — its freestanding design means it stays standing when you move the vehicle, which is a genuinely useful feature on longer camps.

Do I need to season my annex? Polycotton canvas tents sometimes need seasoning but polyester and ripstop polyester annexes do not. Check your specific annex documentation to confirm.

Our Pick

For most Australian campers, the Darche Hi-View/Panorama 1400 Annex is the best annex you can buy — assuming you’re running one of those tents. It’s purpose-built, excellent quality, comes in three drop heights, and is priced fairly for what you get.

If you’re running an iKamper Skycamp 3.0 and want the absolute best, the iKamper Annex Plus is in a class of its own — freestanding, massive, and genuinely impressive. Just factor in the premium price and check current Australian dealer availability.

For budget campers on the Adventure Kings setup, the matched Adventure Kings annex at around $199 is a no-brainer addition.

Whatever you choose, adding an annex to your RTT setup will transform the way you camp. Combined with a quality tent, it’s about as close to glamping as you can get without wheels under the bedroom.
