Hi all, I have a 2014 3500 cab and chassis crew cab 4x4 that I want to put running boards on. I keep being told my truck is special and the normal running boards won't work. I measured a friends 3500 crew cab 4x4 and everything measures the same. The only difference I can see is where my def tank is located but it doesn't look like it will cause any issues. Can any one tell me if there is any reason why they won't work? The mounting holes are in the same place, Thanks.
