Alu-Cab Gen 3-R Expedition vs TentBox Classic

The Alu-Cab Gen 3-R Expedition and the TentBox Classic 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 TentBox take noticeably different approaches to the same problem.

The Classic is 9 kg lighter at 67 kg against 76 kg, which on a factory roof rated for 68 to 75 kg is often the difference between a legal fit and a rack upgrade. Floor area is close to identical at 2.73 m² and 2.79 m², so neither wins on sleeping room. Headroom separates them further: 160 cm in the Gen 3-R Expedition against 100 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 Classic uses ABS shell with aluminium frame and stainless steel hardware. Canvas differs too: double-layer 400gsm canvas, hydrostatic head above 1000 mm against stormproof breathable UV-resistant fabric, 3000 mm hydrostatic head. The Gen 3-R Expedition adds a heater or HVAC port, solar-powered ventilation and the ability to carry cargo on the shell, which the Classic does not offer. Closed, the Gen 3-R Expedition sits 7 cm lower on the roof — 28 cm against 35 cm — which is drag you carry on every mile you are not camping.

Which one to pick

Take the Classic if your roof load limit is the binding constraint. Beyond that the feature rows below — heater port, skylight, annex, cargo rails — are where the remaining difference lies.
