i got nothing for ya on the rock issue....no dualie here...but they do really look much better than the overly chrome landing pads that came with my truck...matter of fact it just had too much chrome PERIOD!...hence why i powdercoated the bumpers to match.....
you will like them....and if not, even used you can probably get back near what you paid for them....although im not sure how much to install...i put mine on myself and orderd them from amazon...?
