Here's the ones I ended up with, like I said in my earlier post, $30. They are not full length, so do not offer full protection. I tested it out on a gravel road today that was causing quite a few dings without any flaps, and I didn't hear any after a couple of miles. The issue I was having was rock chips in the 6-8 inches right behind the wheels. These are low enough that they give that area coverage, but as you can see, are not wide enough to accommodate wider tires (I am running 265). The nice thing is that they are very flexible, so between that, and being slightly shorter, they shouldn't catch nearly as bad as anything like the stock flaps.
Also, if you go the flaps route, check out rokblokz. $120.00 for good length, slightly wider, flexible flaps with Tacoma mounting hardware.
