Alu-Cab Gen 3-R Expedition vs ARB Altitude Electric
The Alu-Cab Gen 3-R Expedition and the ARB Altitude Electric are both hardshell tents in the same part of the market, which makes them a genuine head-to-head rather than a comparison across categories. Alu-Cab and ARB take noticeably different approaches to the same problem.
The Gen 3-R Expedition is 30 kg lighter at 76 kg against 106 kg, which on a factory roof rated for 68 to 75 kg is often the difference between a legal fit and a rack upgrade. Inside, the Altitude Electric gives 3.63 m² of sleeping floor against 2.73 m², about 33 percent more, though both are rated for 2. Headroom separates them further: 160 cm in the Gen 3-R Expedition against 118 cm, which is the difference between sitting up to dress and doing it lying down. Alu-Cab does not publish a list price for the Gen 3-R Expedition, so a direct cost comparison means getting a quote from a dealer.
The Gen 3-R Expedition uses aluminium hard shell with insulated roof and base; the Altitude Electric uses fiberglass. Canvas differs too: double-layer 400gsm canvas, hydrostatic head above 1000 mm against 380GSM poly-cotton canvas. Closed, the Gen 3-R Expedition sits 9 cm lower on the roof — 28 cm against 37 cm — which is drag you carry on every mile you are not camping.

It is the most expensive and heaviest of ARB's current rooftop tents.

Which one to pick
Take the Gen 3-R Expedition if your roof load limit is the binding constraint. Take the Altitude Electric if you need the sleeping room more than you need the lighter tent. Beyond that the feature rows below — heater port, skylight, annex, cargo rails — are where the remaining difference lies.
