Upgraded StructureWorking on the knowledge gained from over three years of both sales and testing of prior models, along with valuable feedback offered by ARB's broad worldwide customer base, ARB made significant improvements to the structure of the tent base and frame. The base is now manufactured from vacuum laminated ABS materials, offering superior strength and insulation. The roof bows have been increased from 16mm raw aluminium tube to 25mm anodized aluminum tube, increasing the erected stability of the entire tent structure and decreasing excessive movement in adverse weather conditions.

Hinges have been upgraded from 3mm steel to 4mm braced steel for extra strength and all plastic fittings have been upgraded from PVC to a more durable Nylon based material. The veranda now incorporates dual extendable bows which allow for better tensioning of the tent canvas as well as increasing internal space. Fully adjustable, these are locked in place with a simple screw type locking ring.

Overall, everything is more ‘rounded’, allowing easier use of the cover, elimination of injury from sharp parts and a better appearance.



The Series III canvas offers greatly improved water proofing ability with the increase from 240gsm (Grams Per Sq. Meter) rip-stop canvas to a heavier 300gsm Poly/Cotton rip-stop canvas with Polyurethane coating. All stitched seams now feature welded seam tape to eliminate seepage through needle punch holes.

The small eyelets that were used for locating the window rods in the aluminium frame have been replaced with over locked openings, allowing for easier location.



 Fly Sheet:

Fly SheepThe fly sheet fabric has been upgraded from 180D Nylon to 300D Oxford polyester. This coupled with a Polyurethane coating has increased the quality and doubled its water shedding ability. In addition, all toggles have been elasticized to reduce annoying flapping noises when windy.


The mattress has been upgraded from single layer extruded foam to high density bonded chip foam, increasing comfort and durability and reducing the likelihood of collapsing from extended use.


Cover Zippers DetailThe cover has been upgraded from 560gsm (Grams Per Sq. Meter) laminated PVC that had limited UV resistance to a UV stabilized 9000gsm laminated PVC. All seams are now sealed with heat welded seam tape to prevent water ingress.

Previous covers incorporated a self mending spiral zipper, however with rough uses combined with dust ingestion this could be damaged beyond repair. All Series III covers now have a larger, No. 10 Vislon zip for increased durability.




The two cover straps have now been upgraded to three and run perpendicular to the ladder, reducing the chance of cover damage and preventing billowing during travel.


Along with all the other aluminum components, the ladder is also upgraded from raw aluminum (that was prone to oxidization) to a more durable anodized finish.ARB RTT Ladder

The locking pins now have a larger rounded head to reduce cover wear and improve handling.
