Spacious for one and snugger for two, the tent has three windows offering a commanding 360-degree view from your Vertex Lite when the door is open. The built-in 3-inch foam mattress offers high levels of comfort after a long day on the hill. Mounting system: Most roof tents must sit on lateral roof bars (not just factory-fitted side rails!), so you'll need these too. It's easy to find the correct ones for your car by using the online search filters provided by retailers like Halfords. Another trusted retailer would be Autodoc.

Once you’ve ensured your vehicle’s roof bars [1] are secure and parallel, the Vertex Lite should be lifted by two people (or a hoist) and slid on from the side, onto the roof bars. Ensure it sits in line with the centre of your car so not to obstruct the boot (tailgate) when opened.

Access: Roof tents come supplied with a telescopic ladder that allow you to easily and safely access the tent. Though, if you're climbing and descending in the dark, you might want a head torch.

Hard or soft shell: Roof tents that collapse down into a sleek hard shell are more aerodynamic and aesthetically satisfying than those that sit under a heavy-duty soft cover. The latter will also save you a little bit on fuel too, but they cost more to buy.
