Manik "Rock Bars" are not sturdy VS. the factory ones. The moutning points are only in two spots and are more for looks from Manik. The look godd, but won't support your rig if you get into that type of situation. You'll only result in bending those into your rig and casuing more damage. Also, while your protecting the rig, get the factory UC protection. Chance are, if you are worried about hitting your rocker panels, you'll hit the UC first.
For what your dealer was charging, they wern't doing you any favors. If you can do the install yourself, buy from one of the websites at a slightly discounted price.

Here and see what kind of price you can get. I tried to find the numbers for you, but they are filed away somewhere. Maybe someone else can chime in and list the PN's for you.
