Alu-Cab RT-4S 4 Sleeper Roof Top Tent

Please Contact Us for Availability 817-330-4466

The RT-4S was born from real-world demand. After the success of our ModCAP Family Camper, customers wanted a rooftop tent version – something just as spacious, without the full ModCAP setup. So we built it.

The result? A fully standalone, 4-sleeper rooftop tent designed for families, overlanders and anyone who needs more room up top. Thanks to its flip-out bed design, the RT-4S adds extra headroom and sleeping space, beyond what typical clamshell tents allow.

It’s the largest 4-sleeper hard-shell RTT on the market, offering over 4.5m² of sleeping space. Mount it on an SUV or canopy, with side-opening flexibility to suit your setup. The integrated telescopic ladder stows inside and supports up to 150kg | 330lbs when deployed.

Why the RT-4S?
 
Because space, flexibility and comfort matter, especially when you’re deep in the wild. The RT-4S gives you more room, smarter layout and total control over how you camp.
