broncophil - Thanks for the compliment!
JWAustinVTX - The taillights were not as easy of a swap as I thought they would be. LED vs. incandescent being the biggest issue. I've tried resistors but they only work for a couple of months. I'm in the process of getting this fixed permanently and will keep everyone posted when they are working 100%.
ebelp - I am referring to the side rails only even though the shallower crossrails seem enticing as well. Here is a picture of the Escalade side rail which I prefer over the black plastic / partial chrome rails that come with the Yukon/Tahoe...
showtime1k - It appears that the console cup holder lids are a bit more complex to change out than compared to the late models. It seems that the vinyl wraps around the cup holders on an LT for example where the LTZ the vinyl wraps to the rectangular opening and the lids are wrapped too. Maybe that upper vinyl piece and cup holders come off as a single piece.
