There are two accessories that can upgrade a truck's utility like no others: truck racks and tonneau covers. One gives your truck multiple hauling options for large items, the other keeps items in your bed safe, secure, and protected from the elements. It's no wonder so many truck owners want to have both items so they can get the best of both worlds. However, not every tonneau cover is going to be compatible with a rack system, and those that are will be limited to particular rack designs. To help you take the guesswork out of combining a rack with a tonneau, we explore how these two accessories interact so you can find a truck rack that works with your truck bed cover.
