Hey guys! I'm a total newb. But very excited to have recently become the owner of a 2008 Prius Touring. Being a pretty avid outdoorsman, I tend to carry hiking boots, and all sorts of other stuff with me that has the potential to be dirty and gross, and I'm looking to protect my tan interior cargo area with a mat. I live in an apartment with no workspace, so I'm not particularly interested in making my own. The one thing that keeps coming up when I'm looking is: "With Cargo Extension". I've probably just not done enough research to be familiar. Can someone elaborate on this option and how I'd know if I have it? I tried searching the forums, but wasn't able to locate another post- so sorry if I missed one. Thanks!
