I’m selling my 5 year old Extang Solid Fold tonneau cover for a Chevy Colorado long bed (6’2”). I’m assuming it would also fit on a GMC Canyon, but can’t say for sure. It is is perfect working order, I just decided to switch to a full camper shell. Honestly, this tonneau cover actually keeps the water out better than the expensive shell. Only a tiny bit of water gets in at the corners, and only in the heaviest of rain. It has pretty clever levers that hook under the bed rails to lock it closed. (Only is really locked if you also have a locking tailgate) It attaches to the rails with simple hand tightened twist screws and is very light to move by yourself. Take it off or out it on in 5 minutes or less. I would definitely highly recommend this cover to anyone. Sells for $959 new.
