UnderCover SE one-piece tonneau cover

Is the UnderCover SE one-piece tonneau cover the tonneau covers pick here, or just one of three?

This page lines up the options that fit your truck and points you to the exact part number to select.

The UnderCover SE one-piece tonneau cover and the ACCESS Toolbox Edition toolbox-compatible tonneau cover and the BAKFlip MX4 hard folding tonneau cover solve the same tonneau covers need in different ways. This compare holds what each includes, where each stops fitting, and what each asks of the install side by side; price is read after that, on purpose.
