Welcome, I'm glad to get another 2mode Tahoe driver on the forums.

The birds do the same thing with my Prius. I too have the weathertech mats for the front and rear. The middle row mat did not fit properly. They are 'supposed' to be working on a hybrid specific middle row mat, but I may just try and trim it to fit.

Eat a bowl of ice cream at the creamery for me the next time you go to State College. I moved from PA to Texas when I was 13 and have only made the trip back once.

Cheers,
Tom H in Dallas
