Series III Simpson Roof Top Tent - Annex Included - by ARB

ARB is one of those brands that doesn't need introduction. Its world wide leadership and recognition are well deserved. Top of the line quality and classy, well thought design have maintained the Australians on the top, tendency-setting area of the 4x4/offroad/overlanding industry. 

This roof tent is truly special, it evolved from its predecessor the series II. It's re-design took more than 6 months in the making and a new factory for improved quality assurance. The update incorporates a new design and better materials to increase weight limits, strength, UV rigidity and water resistance as well as an Annex.

This tent is made to provide the most convenient and easy to use experience while car camping where ever you go. It opens and folds in minutes using its bungee cord system that keeps the walls tucked in to speed up the process so you can be back on the road as soon as possible.

The ARB Series III Simpson Roof Top Tent is made by extreme overlanders and thought for the same kind, its construction was guided by people who know by experience what, when and how we need a RTT to be, from its structure and canvas to its outer looks and materials.

It will give you that feel that all ARB products have; high quality and durability. This off the floor tent will fully protect you from the outdoor elements and wildlife. Just imagine your next journey with such a great tent, classy, durable and high quality.

Why the ARB Simpson III Roof Top Tent Outperforms the Competition

The ARB Simpson III Roof Top Tent isn't just another soft-shell tent—it's a proven system built on decades of Australian outback testing. When you're investing in a rooftop tent, you want reliability, quick setup, and genuine 4-season capability. The Simpson III delivers all three.

2-5 Minute Setup That Actually Works

Setup speed matters when you roll into camp after a long day on the trail. The ARB Simpson III Roof Top Tent uses a proven bungee cord and gas strut system that lets you deploy the tent in under 5 minutes, even on your first try. No complicated poles to assemble, no confusing instructions—just release the straps, unfold, and you're ready to sleep. The included annex deploys just as quickly, giving you a full changing room or gear storage area in minutes.

Compare that to budget soft-shell tents with complicated pole systems that can take 15-20 minutes, or even some hard-shell competitors that require adjustment and fine-tuning. The Simpson III's design is refined from years of real-world use—it just works.

Built-In Annex Adds Serious Versatility

What sets the ARB Simpson III apart is the included annex—not a cheap add-on, but an integrated part of the system. This gives you a full-height changing room, gear storage space, or even a sheltered area for kids. The annex zips directly to the tent with the same quality construction as the main tent body.

We've seen customers use the annex as a dog shelter, a private bathroom area with a portable toilet, extra sleeping space for kids, or simply as a mudroom to keep dirty gear out of the sleeping area. That versatility turns a 2-3 person rooftop tent into a legitimate basecamp setup.

True 4-Season Weather Protection

The ARB Simpson III Roof Top Tent is engineered for extreme conditions—scorching desert heat, mountain snow, torrential rain, and everything between. The 280gsm poly-cotton canvas is UV-resistant and breathable, preventing condensation buildup that plagues cheaper all-polyester tents. Heavy-duty zippers won't fail after a season of use, and the waterproof PVC floor keeps you dry even on multi-day rain trips.

The window awning system is a thoughtful detail—it lets you keep windows open for ventilation during rain without water pouring inside. Four large windows with mesh screens and privacy panels give you temperature control options that cheaper tents simply don't offer.

Quality Construction From a Proven Brand

ARB has been building off-road equipment in Australia since 1975, and the Simpson III shows that heritage. The mattress is high-density bonded chip foam—not the cheap extruded foam you'll find in budget tents that compresses flat after a few trips. The tent body uses reinforced stitching at stress points, heavy-duty YKK zippers throughout, and aluminum poles that won't bend or break.

At 154 lbs (including ladder), the ARB Simpson III Roof Top Tent is substantial but manageable. That weight comes from quality materials, not unnecessary bulk. The included telescoping ladder is sturdy enough for adults climbing in and out multiple times per night without flexing or feeling unstable.

Compatible With Your Overland Setup

The ARB Simpson III mounts to any roof rack system with adequate load capacity (check your vehicle's dynamic roof load rating—typically 165+ lbs required). Whether you're running a Prinsu, Rhino-Rack, Yakima, or Thule system, the mounting hardware adapts to standard crossbar configurations.

We recommend pairing the Simpson III with ARB's awning systems for a complete shelter setup, though it works perfectly as a standalone tent. The neutral design integrates cleanly with any vehicle build without looking like an afterthought bolted to your roof.
