Manuals & Guides
FAQ
How long does it actually take to set up the Mamba III?
Setup truly takes less than a minute in practice. You unlock two latches on the shell, pull down the telescoping aluminum ladder, and insert the two window support rods. That's it - you're ready to sleep. Closing it back up is the same process in reverse. It's one of the fastest-deploying hard shell roof top tents available.
What vehicles is the Mamba III compatible with?
The Mamba III uses a universal adjustable aluminum channel mounting system that fits most roof racks, crossbars, and bed rails. It's compatible with a wide range of trucks, SUVs, and 4x4s. Always verify your vehicle's roof load rating before installing any roof top tent - the dry weight of this tent is 220 lbs., so make sure your rack and vehicle roof are rated accordingly.
Are the cross bars compatible with Thule and Yakima accessories?
Yes - the two included cross bars are fully compatible with Thule and Yakima accessories, giving you flexible options for carrying bikes, kayaks, cargo boxes, and other gear on top of the closed tent during travel. The bars can also be removed entirely if preferred. Load capacity is 45 lbs. while the tent is open and 100 lbs. while it's closed.
Will the Mamba III keep me warm and dry in bad weather?
Yes. The Mamba III is built for four-season use. The shell seals with a military-spec weatherproof gasket, the fabric is rated to 3,500 PU waterproofing, and the base is an insulated 1" honeycomb aluminum panel. The included anti-condensation mat also helps manage moisture buildup inside the sleeping area on cold nights. Verified owners have reported staying warm and dry through severe wind, heavy rain, and freezing temperatures.
Does the Mamba III come with a mattress?
Yes - a 2.5" high-density foam mattress is included, along with an anti-condensation mat that sits underneath it. When the tent is closed, the interior space is large enough to store your bedding inside, so you don't have to pack and unpack sleeping bags every time.
What optional accessories are available for the Mamba III?
Overland Vehicle Systems offers several compatible accessories, including an HD Mamba Awning Bracket Kit, an LED Light Kit, and a Tent and Awning Organizer. These can be added to your order at the time of purchase or sourced separately.
