Its now two weeks with the '14 Silverado & I'm stumping myself on the mud flaps. I've been looking at my options for most of the week. I really like the OE molded type but don't really want to drill holes in the fenders & bed side, fight with the seam sealer on the front. They have a flat set with the same drill issue. Other choice is a set of Weathertechs but they look like they somewhat smaller/not as high up the wheel opening. I know I'll be spending more that I care to but as the saying goes "good is not cheap, cheap is not good." After this I'll be looking into stainless step tubes, Weathertech floor mats front & rear, & a good spray in bed liner. I atleast got the K&N filter (like hours after buying it) in, put in a set of Phillips LED back up bulbs.
