Pickup truck owners often seek to combine tool boxes and tonneau covers for added functionality. Several options exist, including roll-up covers like the Access Toolbox Roll-up Cover and folding covers from Extang, which feature a proprietary 'L-Channel' design to create a sealed connection with tool boxes. Additionally, products like the 2-in-1 Tonneau & Toolbox Combo by Stowe Cargo Systems provide integrated solutions. However, combining these features has downsides. Users may experience reduced bed space and limited access to tools, especially with sliding drawer tool boxes that occupy the entire bed. Furthermore, no tonneau cover is completely waterproof, raising concerns about potential water exposure to tools. While the combination offers benefits, such as improved fuel efficiency, the trade-offs must be carefully considered.
