Just my two cents on the molded mud flaps. I bought a set for my 1999 1500 4x4 sport from the dealer and then had them install them when I went in for service. I hated paying for that but I lived in an apartment at the time and didn't have the tools available to do it myself. Anyway, after they were installed, I could feel a vibration coming through the drivers side floor when I was traveling above 50mph on the highway. I didn't experience it before the mudflaps were installed so I checked them when I go home from work that night. The rear "lip" of the mudflap that comes in contact with the rocker panel below the door was rubbing back and forth from the wind and in a single days use, it had worn through the clear coat and into the paint. I laid a bead of silicone to hold the rear of the flap in place and that stopped the problem, however, I had to reapply the silicone approx every month. I could have cut the flap back, but I thought it would look like crap. Anyway, I have had crappy luck with the molded Mopar mudflaps. If you buy them (they look great), make sure to install them yourself and try to put something to prevent the rubber lip on the flap from contacting the rocker panels. I had no problems with the rear flaps. Just my experiences.
