I’m curious if there is and difference in location of the cab mount locations between a standard crew cab truck and a cab and chassis crew cab truck. Specifically in relation to the rocker panel. I ordered some running boards that do not fit. They attach to the front cab mount and rear cab mount and now the company is saying that the issue is my chassis cab truck is different than a standard bed equipped truck. Anyone have information that could help. My truck is a 2018 3500 4x4 dually with a Cummins. Thanks
