Installation Guide

Installation Manual

Product Information

TheMamba Clamshell Roof Top Tent is easy to install and compatible with most roof racks. Simply lift it onto your vehicle and use the included stainless steel hardware following the provided instructions. Always check roof rack compatibility beforehand.

Please note that it’s very important to check your owner's manual, or to contact your vehicle's manufacturer, to get information on vehicle load capacities and warranty information before installing the roof top tent. Here are a few questions to ask:

  • What’s the vehicle’s Static Weight Capacity? This confirms that your vehicle and your rack will support the weight of your tent, plus everyone in it and their sleeping gear.
  • What’s the vehicle’s Dynamic Weight Capacity? This is the force exerted on your car and rack while you're driving, so it will be a separate spec for your vehicle and rack.
