I just purchased a clear, one size fits all, floor mat from Advance Auto. It was on sale for $8.88 and it isveryhigh quality with a large drip edge all the way around it. The best part is it looks like it was designed to fit the 08 Tahoe....the fit is perfect. I like the factory mats for general use but was looking for a clear mat that I could put over the top of the existing mat when conditions warranted it. This one was a real surprise.

 

Is this mat for the cargo area?
