Ideal for Jeep Wranglers, but compatible with a wide variety of car roof racks, the Smittybilt Overlander occupies the squarely affordable end of the spectrum. It’s relatively lightweight, built to last, and further bolstered by a host of terrific features. That includes LED strips, side windows with mosquito netting, a telescopic ladder, a sunroof, and more. Upgrade to the XL version to accommodate a few extra rooftop campers.
