Alu-Cab RT-4S 4-Sleeper Rooftop Tent

Short Summary

The Alu-Cab RT-4S is Alu-Cab’s biggest rooftop tent yet: a fully standalone, 4-sleeper hard-shell RTT with a flip-out bed design for extra headroom and family-friendly sleeping space. It’s solar power-ready, includes a mattress, and features a built-in heater vent for more comfortable cold-weather camping.

Why This Product

When you’re camping as a family (or you simply want more room), standard clamshell rooftop tents can feel tight—especially on longer Western Cape trips where you need comfort, storage, and a smarter layout. The RT-4S was built from real-world demand for a rooftop tent version of Alu-Cab’s family-style space: more sleeping area, more headroom, and flexible side-opening options—so you can stop stressing about space and start enjoying the trip.

Key Features

• Massive 4-sleeper sleeping space – mattress included with a 2235mm × 2050mm sleeping area

• Flip-out side bed design – creates extra headroom and space compared to typical clamshell RTTs

• Left- or right-side opening (LHS/RHS) – choose the best orientation for your canopy/awning/kitchen layout

• Lightweight aluminium frame – strong structure for overlanding and touring

• Double-layer 280gsm UV-resistant ripstop canvas – designed for harsh South African sun and weather

• Built-in heater vent + raised external air vent – better airflow and cold-night compatibility

• Integrated telescopic ladder – stows inside; supports up to 150kg when deployed

• Dual-colour interior LEDs (red/white) – 2 lights with dedicated switches to protect night vision

• Power access inside the tent – 2 × USB, 4 × Type C, 2 × 12V sockets

• Smart internal organisation – 12 canvas storage bags for essentials

• Marine-grade skylight – UV-resistant clear PVC for light and visibility

• Fly sheet included – extra protection in changing conditions

Ideal For

• Families wanting a true 4-sleeper hard-shell rooftop tent in South Africa

• Clients building an SUV or canopy rig for weekend getaways and longer overlanding routes

• Overlanders who want space and headroom without moving to a full camper conversion

• Campsites where side-opening choice (LHS/RHS) matters for awnings, doors, and access

• Anyone prioritising comfort upgrades like heater venting, storage, and integrated power
