mine had mudflaps with 4x4 insigna modled on and painted white. on all 4 tires at that too.

My flaps have the Ram insignia (the sheep's head). I wonder if yours, or mine, got swapped at some point.

I've seen pictures of the 2nd gen rams on the catalog with 4x4 mud flaps and the ram logo. They may both be factory. I think it may have been an option?
