I transfered this rack from my old F250 on to a 2018 Tacoma short-bed. The tonneau cover is a Pace Edwards Ultra Groove with a t-slot that accepts Yakima or Thule towers. In this case, Yakima Launch Pad 1's.

Due to the short length of the bed, rear-ward facing bikes need to be outboard in order to clear the cab. With a long bed, it might be possible to get 5 bikes on there...not that 5 adult males can fit in the cab.

There is approximately 27" (686mm) between the inner trays, so the plan is to put a Kuat Mini Skinny between them. This may allow a 5th bike, and more gear storge.
