i bought the load warrior, which yakima makes. i then bought the spare tire holder they sell to fit onto the load warrior. thats it!!! its pretty simple setup, and i really like it. i have my spare up there right now. ill post a pic to show ya.
i also hooked up lights to the same rack, works very nicely. heres a pic of that.

of course, this pic is BEFORE i put the spare tire in the rack. ill get a pic of it in there if u want...
