i don't think its very functional. i wheel tight trails where it would be in the way. i think it is inspired from baja trucks. and just crosses over for looks. i don't think its good for pushing it up an incline untill your front tires hit. for that purpose you'd be better off with shorter bumper, longer wheelbase for better approach angle.
i don't know though, i don't have experience with it, or know anyone with it, just my initial opinion
