for the side steps...Cervinis hands down...they bolt into the side of the bed thru the stock mounting holes.
As for the roll pan...that is a personal preference. My self I like Cervinis, Lund, Street scenes and sir michaels in that order.
street scenes looks the best. the whole kit is around 444$ but it requires alot of work to put it on. the kit comes with the front and rear smooth steps an roll pan. this is where i ordered it from.Street Scene Fiberglass and Urethane Rear Roll Pans Hidden Hitches
I just installed cervini side steps on my truck and SS rollpan.
My friend installed the SS side steps and Cervini bumper.
I wish I would have chosen the SS. Although they take more work to make them fit properly, the cervini's left too much of a gap between the bed and the step itself when lined up properly.
This pic is incomplete, no handle or tailgate strip on yet.
The color is not 100% yet, need to do a couple coats a little darker to get it right.
