These running boards fit without issue on our Ram Crew Cab. Had a small problem at first with some missing mounting brackets, but RealTruck Customer Service was excellent in the manner that they expedited replacements. There wasn't any drilling required for this truck model/year and the boards were easy to mount. The provided instructions were simple to understand and the included photos were useful too. It is beneficial to read through the instruction before starting though.
I will mention that the carbon steel mounting brackets are only painted and the fasteners appeared to be painted also (versus being manufactured from corrosion resistant steel). With that in mind, I am hoping that they last for the life of the truck without requiring a lot of maintenance. I'd be more concerned if we were living in an area where the roads are salted in the winter.
As our vehicle came with factory 20" wheels, the running boards are a big help for my wife and I getting into/out of the vehicle. For reference, the top of the installed running boards are about 10 1/2" below the door sill and 13 1/2" above the ground.
