I am trying to decide on a set of Nerf Bars for my 2011 1500 Big Horn. I have it narrowed down to the Go Rhino Dominator model D24099B and the N-Fab model D0973QC-TM. Both of these are cab length, not wheel to wheel. I do have the factory molded mud flaps as well. My questions are these....1. Will the factory mud flaps interfere with the bars and 2. are there any holes that need to be drilled?
Anyone who has these on their trucks and could shed some light, I would appreciate it.

 

Glad I could be the first to post. I'm in the exact same boat, looking at the same bars. But I have an edge.. I sell them at my company, and get them at cost. They are the exact same bar. Go Rhino gets them from N-Fab and puts the little stainless pad on them. Go with the cheapest price, because it's the exact same product. I had this conversation with the boss yesterday, have the cab length ones on a display in my showroom. Although they've got a coat of Line-X on them we did.

 

No drilling
No interference w/factory splash guards
Just be sure to order the right length to fit your truck

If it's necessary to remove the cab-to-frame bolts, as it sometimes is, do not reassemble without first using some thread-locker compound on them such as Lok-Tite. I also highly recommend reinstalling the cab-to-frame bolts with a Torque wrench and take them down to 80 ft lbs (per factory spec).
