I have a WeatherTech. It works great. Doesn't look too bad either. Currently, I have it in an Acura CL, only thing that bothers me about it is that I can't access some of the tie downs to have my cargo net taught. Other than that, I'm please with it. Thing is, don't know how it would work with the dual deck in the 4Runner. When I'm ready to get a Runner, I most likely would get another WeatherTech.
