Nice set up for sure! I have seen many trucks around here like that. In fact, one of my fellow racers has it on his tundra. I just opted for the folding bed cover and I fold it back out of the way with the board across the back with fork holders on it.
That's a lot more money than I had to spend... This was done on a tight budget.
I tried to find the "How do you haul your bikes" thread and add it to that, but after 30 minutes of searching, couldn't find it.
This will look very nice once I paint it to match, and I am using clevis pins to attach it so I can remove it easily when hauling mulch, etc.
