The Mahindra Thar Roxx overland build

The 3-door Mahindra Thar is a brilliant overland base with one persistent tax: it is short and narrow, so the moment you put a tent on the roof you raise a high centre of gravity even higher, and you feel it in crosswinds on the Leh highway and on off-camber tracks above Kunzum La. The Thar Roxx removes most of that tax. Its wheelbase is roughly 2,850 mm against the 3-door's 2,450-odd, its track is wider, and it keeps the same body-on-frame ladder chassis and — on the 4XPLOR trims — a genuine low-range transfer case. The result is a vehicle that carries a rooftop tent with markedly more composure.

In practical terms this widens your choices. On a 3-door Thar we steer owners hard toward the lightest tents because every kilo high on the roof matters more on a short wheelbase. On the Roxx that pressure eases: the flagship AutoNest 120 and the hardshell Bison61 sit well on it, and you get the five-door's real interior and boot to carry water, recovery and tools down low where they belong. You are building on a platform that was, for the first time from Mahindra, designed with space and stability in mind rather than pure short-wheelbase agility.

None of this repeals the basic discipline of an overland build — light roof, heavy items low and inside — but the Roxx gives you far more margin to get it right. Treat that margin as permission to carry what you actually need for a self-sufficient Spiti or Ladakh trip, not as licence to stack a heavy fixed rack, a roof box and a tent all at once.

For most Roxx owners the honest best answer is the AutoNest 120. It is our fully-automatic hardshell — one button raises and lowers it — so on a vehicle that is finally stable enough to carry a proper tent without drama, you get the fastest, most weatherproof setup we make. Its closed profile is low and aerodynamic for the long highway hauls to the mountains, and its shell shrugs off the snow load that catches softshells out at a high camp.

If you want a hardshell at a friendlier price, the Bison61 is the pick: a clamshell that packs down clean for transit and opens in seconds, well matched to the Roxx's longer roofline. And for owners whose trips lean genuinely cold — winter Spiti, high camps above 3,500 m — the CampTop 300Lux earns its place with dual heater ports designed to take a diesel heater's ducting and an all-season thermal mattress. The Roxx's stability means the 300Lux's extra weight over an ultralight tent is a non-issue where it would have been a real consideration on the 3-door.

The one thing the Roxx does not change is the load principle. A rooftop tent's 300 kg base rating is a static, parked figure — what it sleeps under — not a number you drive around with. Your driving (dynamic) roof load is far lower and includes the crossbars, so match tent-plus-crossbars to your crossbar and roof rating, keep the roof to just the tent while moving, and let the Roxx's generous cabin and boot carry the dense gear. If you want the full load maths worked through, our rooftop-tent buyer's guide walks the dynamic-versus-static distinction with examples.
