Overland Vehicle Systems Warranty
At a glance: coverage depends on the line: limited lifetime on Expedition truck cap structure and XD awning frames, 6 years on XD tents and XD awning fabric, 4 years on HD tents and awnings, 2 years on LD tents
This is Overland Vehicle Systems's policy, not an NVMOS policy. OVS doesn't publish one warranty document. Its product pages say coverage and terms vary by product, so we've pulled the terms from each OVS product line's own pages and summarized them in plain English. Where an OVS page shows a generic warranty badge that disagrees with the product's own warranty text, we use the product text. The manufacturer's official terms always govern and can change without notice. Last reviewed on nvmos.com: October 16, 2026.

HD Mamba 2 Person Aluminum Clam Shell Roof Top Tent
The HD Mamba is a clam shell hard top tent for people who are tired of wrestling a fabric cover at the end of a long day. Two latches release the lid, gas struts lift it, and after the ladder and two window rods go in you are set up in under a minute. Closing it is the same steps in reverse.
The shell and the 1 inch insulated base are both honeycomb aluminum, sealed with a military spec gasket and put together with 304 stainless steel hardware. The 280g rip-stop poly cotton body is FMVSS 302 certified with a 3500 PU waterproof rating. Two removable crossbars on the lid carry extra gear and work with Thule and Yakima accessories, and t-slot channels take small recovery gear or lights. See how it compares with our other roof top tents.
Universal. It mounts with adjustable aluminum channels to vehicles with a suitable factory or aftermarket roof rack or bed rack. Make sure your rack is rated for the tent's 220 lb dry weight.
The tent comes with a 2.4 inch mattress over an anti-condensation mat, two removable crossbars, and an adjustable interior pop-up strut to support the lid when the crossbars are loaded. It does not include a skylight, interior lighting, a travel cover or an annex room. Closed it measures 90.5 x 55 x 6.5 inches, open 90.5 x 55 x 59 inches, and the sleeping area is 90 x 51.5 inches. At 220 lb dry, this is a two person or forklift job to install. This one ships by freight truck, so plan on a delivery appointment. Not sure it fits your setup? Call us at (920) 249-7744 and a real person will check it.
