I am just going to throw this out there for all the people that are doing rack research.
I am in the midst of it too. If your not Leif or willing to drop a few K on a custom rack here is a sweet alternative.
Contracter Kargo Master racks. They make them in sizes for just about
every pickup, canopy or no canopy and for vans too. I am buying one
this weekend for less than $500 bucks!!!!
