About This Product
The Mars Horizon is a fold-over hard shell rooftop tent that opens with its own ladder: pull the telescopic ladder, use it as a lever to flip the shell, and climb in. The manufacturer quotes under a minute from closed to pitched for two people, with no tools. Closed, it sits at a compact 56.7 by 42.1 inches and 11.4 inches tall, which suits narrower roof platforms and keeps highway drag down.

Ladder-Assisted Deploy
The telescopic aluminium ladder doubles as the opening lever, so there are no straps or handles to wrestle. It is rated to 330 lbs and removes for storage. Spring poles prop out the rear awning for extra covered space outside the tent.
Made for Weather and Rough Roads
The aerodynamic hard shell protects the mattress and bedding from rain, UV and dust while you drive. Inside, an aluminium alloy frame with reinforced nylon joints handles washboard roads, and double-layer silver-coated fabric reflects heat, insulates and keeps water out.

Comfortable Once You Are Up
A mattress, a thermal insulation liner for shoulder seasons and an interior light bar come built in. Power cords on both sides let you run lights, fans or chargers from an auxiliary battery.
Universal Rack Fit
Works with Front Runner, Rhino-Rack, ARB, Yakima, Thule and most factory crossbars.
Two T-Bolt Lengths
M8x50mm and M8x70mm T-bolts are both included.
Compact When Closed
56.7" x 42.1" x 11.4" on the roof.
All In the Box
Tent with mattress, insulation liner, ladder and tool bag.
