Overland Vehicle Systems Sidewinder Aluminum Rooftop Tent

OVS's Sidewinder Aluminum Rooftop Tent is a side-opening, 2-3 person, high quality overlanding home. Made from the same material as OVS's fan favorite the Mamba III, this tent brings all of the same benefits with one key adjustment.

As a side-opening tent, the Sidewinder has a unique design benefit in that headroom is consistent across the interior. With most Clamshell designs and many RTTs headroom gradually increases to a point. Overland Vehicle Systems Sidewinder Aluminum Rooftop Tent figured out how to maximize interior space in a way that differentiates it from similar tents.Overland Vehicle Systems Sidewinder Aluminum Rooftop Tent

Like it's popular cousin the Mamba III, the Sidewinder features high quality aluminum, 600D waterproof rip stop body, functional and removable cross bars for additional exterior storage, a built in 2.5" mattress, and an anti-condensation mat. Opening this tent is quick. Less than one minute thanks to the it's gas struts. Just unhook the latches and watch the tent unfold.

This tent will fit on nearly any vehicle with an adequate roof rack system. Just make sure your vehicle is equipped to handle this tent's 185LB weight. With additional T-slots this tent allows you to increase your campground space and easily add on an awning or annex. Experience the outdoors in comfort and style with the OVS Sidewinder.
