I installed the BedHead on my 2001 Tundra with dealer installed bedliner. The device would not work on the hard plastic rails, so I had to cut out a section and install it to the metal rail. The fit is not that great. The unit will roll off the rail with a good tug. I initially tied down the bike to the stock tie-downs on the opposite side of the truck bed. After a few hours of driving I noticed the unit was rolling off the rail again. I eventually redid the rigging to use the tie-downs on the same side of the bed, along with a single tie to to opposite side. I'm either going to figure out a way to bolt the rack to the bed rail or return this unit for a bolt-on version.
