Then there are the folding units that go "over" the bed rails, hence with those tonneaus you will not be able to utilize the stake pockets for strap hooks or add rails over your bed rails if you have use for that. Undercover and Bakflip both install into the bed. I believe the extang units install over the bed rails.
Yes, the Extang installs over the bed rails. No it does not impede the use of the stake pockets so long as your rail covers have the holes cut in them for stake access. You generally wouldn't need use the stake pockets unless you remove the cover anyway.
That said, in addition to the factory strap hooks in the bed, there are a variety of strap hooks that attach to the bottom of the rail and don't interfere with the cover, Extang has their own line, as well as other 3rd parties.
