Today I received and installed the classic Model 4060 Undercover Tonneau. I'm old and I did it by myself. It's not that heavy or awkward.
Contrary to a post on this forum the OEM MultiTrack cleats CANNOT be used while this tonneau is on the truck. The installation instructions clearly state:
"Before you begin installing the mounting system, you must first remove the MultiTrack cleats. The MultiTrack cleats cannot be used while the cover is mounted. Cleats can be used while the cover is uninstalled"
I checked for clearance after my install and they do interfere with it closing. Stupid me for regarding an ignorant post as decent advice. I'll purchase some nuts from grainger posted by a member for the track.
I wanted to buy an Armor Lid after seeing it in the Toyota showroom when I bought my truck, but it's out of stock from the manufacturer until at least mid March and I needed one now.
I'm glad in the end I bought this Undercover. It will be easier for me to take on and off by myself. The fit is very nice and the installation easy.
Cost was $665. shipped to California. Locally the best price I got was $799 plus tax.
