I always thought so, too, and had pretty much written them off. The weather tech ones in Turbo Todd’s pics have me rethinking that. I might actually put a set on.
No offense to Turbo Todd, but no... don't do it. Looks absolutely atrocious, go back and really look at the picture where you can see both the front and back wheels with the flaps.
Egads... immediately calls to mind some 93 year old driving his truck 47 mph in the fast lane with a blinker on.
And once again, seriously... no offense to TT. I'm glad he likes them, and it'll definitely keep mud/debris/rocks from flying up. But I'd rather have to deal with those things than alter the look of the truck that dramatically and... once again, no offense... that badly. Yikes.
