The Horizon uses its telescopic ladder as the lever that flips the shell open, so deploying it is one motion rather than a wrestling match. Closed, it takes up only 56.7 by 42.1 inches on the rack, which suits narrower roof platforms, yet it opens to an 82.7 by 49.2 inch floor for two adults. A thermal insulation liner and an interior light bar are included rather than sold on top, and power cord passthroughs on both sides let you run lights, fans, or chargers from an auxiliary battery.

Product Highlights
The Ladder Does the Work
Pull the telescopic ladder and it levers the shell over. No tools, and two people can have it pitched quickly, which is what you want when you are setting up in the dark or the rain.
Small on the Rack, Large Inside
A 56.7 by 42.1 inch closed footprint leaves room on the roof for other gear, and at 11.4 inches high it keeps drag down. Open, you still get a full 82.7 by 49.2 inch floor.
Shoulder Seasons Covered
The thermal insulation liner comes in the box, and the double-layer silver-coated fabric reflects heat as well as keeping rain out, so it works in warm weather too.
Power Where You Sleep
Cord passthroughs on both sides mean you can run the light bar, a fan, or chargers from your auxiliary battery without leaving a door unzipped.
Built for Rough Roads
An aluminium alloy frame with reinforced nylon joints handles the constant vibration of washboard tracks, which is where cheaper rooftop tents start to loosen.
Covered Space Outside
Spring poles prop the rear awning open, giving you a sheltered spot to stand, cook, or take boots off before climbing in.
Fits What You Already Have
Both M8 x 50mm and M8 x 70mm T-bolts are included, covering Front Runner, Rhino-Rack, ARB, Yakima, Thule, and most factory crossbars.

Important Information
- The tent weighs 123.5 lbs before anyone is in it. Confirm your roof rack and crossbars are rated for both the dynamic load while driving and the static load of tent plus occupants, using your vehicle owner's manual and rack specifications.
- The tent has cord passthroughs, not its own power supply. You will need an auxiliary battery or other power source to run the light bar and any devices.
- Do not exceed the 330 lb ladder capacity, and set the ladder on firm, level ground. Take care climbing in and out at night or in wet conditions.
- Install using the supplied T-bolts and instructions, confirm all hardware is tightened correctly, and re-check the fixings after the first drive and periodically afterwards.
- A rooftop tent raises your vehicle height and changes its handling. Note the new clearance for garages and low branches, and allow for the extra weight when cornering and braking.
- Close and secure the tent before driving and in high winds. Stow the spring-poled awning before moving the vehicle.
- Do not use open flames, fuel-burning stoves, or heaters inside the tent.
- Dry the tent fully before closing it for storage to prevent mould and odours.
Frequently Asked Questions
