Triangular X-Frame and ABS Hardshell rooftop tents are two distinct hardshell tent architectures suited to different 4WD touring styles. The Triangular X-Frame (NM-RT006) uses an aluminium honeycomb shell with a dual-channel X-frame for maximum structural rigidity and wind resistance, while the ABS Hardshell Clamshell (NM-RT009) uses an injection-moulded ABS plastic shell for rapid deployment and a lower profile during highway travel. Choosing between them depends on setup frequency, wind exposure, internal space requirements, and vehicle compatibility.

Wind Resistance: Triangular X-Frame Has the Structural Advantage
The NM-RT006 Triangular X-Frame uses a dual-channel X-frame design that provides increased structural rigidity compared to single-channel models and standard clamshell designs. The aluminium alloy honeycomb panel shell is inherently stiffer than injection moulded ABS plastic under lateral wind loading. The triangular roofline geometry also deflects wind more efficiently than the flat-sided clamshell profile.
The NM-RT009 ABS Hardshell clamshell design is aerodynamically efficient when closed its 32cm low-profile height reduces drag at highway speeds up to 110 km/h. When open, however, the vertical sidewalls and flat-top opening present greater wind resistance than the angled triangular structure. In exposed campsites with sustained wind, the Triangular X-Frame provides a more stable sleeping environment.
Verdict: For coastal, elevated, or exposed campsite use, the Triangular X-Frame offers superior wind resistance. The ABS Hardshell performs better aerodynamically while driving.
Internal Space: Clamshell Offers Wider Floor, Triangular Offers Greater Height
The NM-RT006 opens to 212 × 131 × 145 cm (L × W × H), with 145cm peak internal height allowing most adults to sit upright comfortably. The 131cm width is suited to two adults sleeping side by side. The triangular cross-section means internal width narrows toward the foot end, which affects available sleeping width across the length of the mattress.
The NM-RT009 opens to 155 × 200 × 116 cm with an internal sleeping area of 141 × 195 × 115 cm. The 200cm length and 116cm standing height mean the clamshell is shorter overall, but its rectangular floor plan provides more usable width across the full sleeping surface. The 2–3 person capacity reflects a wider, more open interior geometry suited to families or those requiring extra space.
| Interior Factor | Triangular X-Frame (NM-RT006) | ABS Hardshell (NM-RT009) |
|---|---|---|
| Peak Interior Height | 145 cm | 115–116 cm |
| Internal Length | 212 cm | 195 cm (sleeping area) |
| Internal Width | 131 cm (narrows at foot) | 141 cm (consistent rectangular floor) |
| Sleeping Capacity | 2 Adults | 2–3 Adults |
| Floor Plan Shape | Triangular cross-section | Rectangular (full-length usable) |
Verdict: The ABS Hardshell offers more usable floor space for couples or families needing a rectangular sleeping area. The Triangular X-Frame provides greater sitting headroom (145 vs 115cm) and full-length tent access.
Pack-Down and Storage: ABS Hardshell Is Significantly Faster
The NM-RT009 ABS Hardshell deploys in approximately 30 seconds via gas strut-assisted pop-up and packs down in under 1 minute. This makes it suited to multi-stop touring where campsites change daily. No manual fabric folding or ladder adjustment is required for basic setup.
The NM-RT006 Triangular X-Frame opens via 304 stainless steel hydraulic struts with one-person deployment, typically taking 1–2 minutes. The 212 × 131 × 19 cm closed dimensions give it an extremely low 19cm profile — 13cm lower than the ABS Hardshell — which improves aerodynamics and reduces vehicle height clearance requirements when driving to destinations with height restrictions (car parks, underpasses).
Verdict: The ABS Hardshell wins on pure setup speed. The Triangular X-Frame wins on closed height profile (19cm vs 32cm), which matters for daily driving clearance and fuel efficiency.
Shell Material: Aluminium Honeycomb vs ABS Plastic
The aluminium alloy honeycomb panel shell of the NM-RT006 offers a higher stiffness to weight ratio than ABS plastic, better thermal insulation in extreme temperature conditions, and greater resistance to UV degradation over extended periods. Aluminium honeycomb is commonly used in aerospace and transport applications where rigidity and low weight are priorities.
The injection moulded ABS plastic shell of the NM-RT009 provides impact resistance, UV stability, and consistent weatherproofing without the risk of denting or corrosion that can affect aluminium shells in salt-air coastal environments. ABS is lighter to manufacture in clamshell form factors and easier to repair if cracked.
| Material Property | Aluminium Honeycomb (NM-RT006) | ABS Plastic (NM-RT009) |
|---|---|---|
| Structural Rigidity | High (honeycomb core) | Moderate (injection moulded) |
| Thermal Insulation | Higher (honeycomb air pockets) | Moderate |
| Corrosion Resistance | Moderate (anodised aluminium) | High (plastic, no rust) |
| Dent/Impact Resistance | Moderate | High (impact-resistant ABS) |
| UV Stability (long-term) | High | High (UV-stabilised ABS) |
Fabric Comparison: 600D Oxford vs 300g/m² Ripstop
The NM-RT009 uses 600D Oxford fabric for its sidewalls, providing higher abrasion resistance compared to the 300g/m² Ripstop Oxford Plaid used in the NM-RT006. Both models share identical waterproof ratings (3000–5000mm) and UPF 50+ UV protection. The ripstop construction of the NM-RT006 fabric resists tear propagation, which is relevant in bush environments where fabric contact with branches is possible.
Which Rooftop Tent Suits Which Touring Style
The NM-RT006 Triangular X-Frame suits extended overlanding and remote 4WD camping where structural stability, wind resistance, and sleeping comfort over multiple nights are priorities. Its 300kg load capacity, thicker mattress, and dual-channel frame architecture are designed for demanding backcountry conditions.
The NM-RT009 ABS Hardshell suits frequent campsite changes, highway touring, and family camping where rapid setup and a wider sleeping area are priorities. The 30-second deployment and 110 km/h road speed rating are designed for travellers moving daily between destinations.
| Touring Scenario | Recommended Model | Reason |
|---|---|---|
| Extended remote 4WD camping (3+ nights) | NM-RT006 Triangular X-Frame | Superior wind resistance, higher headroom, 300kg load capacity |
| Daily campsite changes / road trips | NM-RT009 ABS Hardshell | 30-second setup, rated to 110 km/h |
| Family camping (2 adults + child) | NM-RT009 ABS Hardshell | 2–3 person capacity, rectangular floor plan |
| Coastal / high-wind environments | NM-RT006 Triangular X-Frame | Dual-channel X-frame, triangular geometry deflects wind |
| Low vehicle clearance requirements | NM-RT006 Triangular X-Frame | 19cm closed height vs 32cm (ABS Hardshell) |
| Backcountry fishing and hunting | NM-RT006 Triangular X-Frame | Enhanced weather protection, elevated platform stability |
| Urban base / national park touring | NM-RT009 ABS Hardshell | Aerodynamic profile, fast pack-down for day trips |
Australian 4WD Compatibility Considerations
Both models mount to standard roof rack systems. The NM-RT006 weighs 79kg (net) and the NM-RT009 weighs 82kg (net). Most Australian 4WD roof racks rated for overlanding carry dynamic loads of 75–150kg depending on the rack manufacturer and vehicle model. Verify your vehicle's dynamic roof load rating before installation, this differs from the static rating stated in the tent specifications.
Common Australian vehicles compatible with both models include the Toyota LandCruiser 70, 200, and 300 Series, Toyota HiLux, Ford Ranger, Nissan Patrol, Mitsubishi Triton, and Isuzu D-MAX, provided the installed roof rack meets the required dynamic load capacity. Check your rack manufacturer's load ratings for your specific vehicle and rack configuration.
