I've used NFab step bars on my last three Ram 2500 trucks. The 2500 platform is a bit taller. They are sturdy, well made bars that don't rattle. Just get the textured surface vs. the painted surface option.
Here's what they look like:
2007 MegaCan - the stock steps were sucked up close to the cab sills and they were narrow. Getting in and out with work boots on was a bit sketchy.
2014 Big Horn - Had the same issue with the side steps that came on this truck. I liked the look but getting in and out sucked, especially in wet, muddy or snowy conditions.
2017 Laramie 2500 - Again, the OEM units were not to my liking so I tried a different NFab step bar model. They work great except I got the painted option. That was a mistake. Rocks and other debris have chipped them up some, especially over this last trip from Arizona to Colorado, Utah, Wyoming, & New Mexico. I will be removing these, prepping them and applying bed liner.
