does anyone know if the molded mud flaps will fit with the factory running boards or any aftermarket ones. im looking at the tubular ones if that helps. thanks!

 

I know you said mudflaps, but just to be sure... you talking actual mudflaps or splash guards??? I have the splash guards on mine with the black tubular running boards from the factory. See pictures in my gallery (my sig has a link). They're hard to see because they're black, but they are there! Mudflaps shouldn't take up any more or less space. You should be fine with either choice.

 

The "Husky" brand does work with the factory tubular boards. I have them on mine.
