Without restating alot. The utilitrack bed and non-utilitrack beds ARE different. According to Nissan literature and phonecalls I have placed to Nissan directly, the utilitrack bed in re-inforced int 22 different places (some of this weight is reflected in the specs for the different vehicles). Nissan claim without the reinforcement the sides could bend inwards. I suppose that depends on the kinds of loads you are strapping in. There are several utilitrack like products though if you intrested.
I addressed some of these issue in another thread:
