Best you can buy
I spent a few months researching tonneau covers and decided that it was worth the investment to try a Truck Covers USA. Glad I did! Looks great on my 2016 Tacoma, keeps water out, was a snap to install (if you do the research and reading it only took me an hour or less alone), incredibly compact when rolled up (8 inch box IS the smallest out there), and is extremely secure. If you're on the fence, just do it. It's worth every penny.
