BAK Revolver X4s

What owners say
Of the five who describe water, three report a dry bed and two a little (about 99.5 percent dry, leaks mainly near the tailgate); none describes wet cargo, and two who came from Retrax covers call it drier. They praise the one-hand roll, the clear rear window and the full bed.
