Very convenient way to have a tool/storage box without using the bed floor or using the bed rails. I currently have the TruXedo Deuce Tonneau cover and the box mounted to the existing rails. It took me longer to unpack the TonneauMate than to install it. I like that I can access the box with the tonneau cover rolled up or just by flipping the front part of the cover. I also have a fifth wheel hitch in the bed and with my RV hooked up I can still access the TonneauMate.
Overall-Very Good Value
Assembly instructions need some fine tuning. 30.5" of the drawer remains underneath the deck when fully extended, not 24 inches. Installation of the tailgate axles in the instruction guide need revision. It was very difficult installing the last remaining wheels on the axles. Just using a 2 x 2" as a spacer is not enough, a 3 foot 2" x 4" as a pry bar is a better description. Wish it had better access to the back of the drawers. I believe it's a good buy for the money.
