The perfect overland truck bed racks are the ones that make the most of the space in your truck's bed, while also keeping your budget and how you plan to use it in mind. Bed racks let you haul larger items like long building materials and ladders that just won't fit in the truck bed itself. Plus, they're made to hold adventure gear such as off-road tools and tents. Picking a bed rack might mean you can't carry things like liquid drums or motorcycles in the bed anymore.
