I agree, no way you can take off the rails too. It would be to expensive and could cause issues down the road. Now if you just want to take off the corss bars, I understand that. I personally like the way it looks without the rails, cleaner in my opinion, as I NEVER plan on tieing anything to my roof!
My LTZ did not have cross rails. However my jeep did and I took them off the day I got the car. If the Traverse would have had them I would have taken them off... Come to think of it, I wonder why it didnt... but it saved me work having to take them off.
I sold my jeep cross bars on ebay, you should have no problem selling the cross bars either here or online.
If anyone has the metal parts that go inside the black decorative casing (why did they put these on if they are TOTALLY useless the way they are??) and wants to be rid of them, please let me know, I seem to be missing them and would like to make my roof rack actually serve its purpose.
I was thinking about this myself. Iblike the sleeker look without them. What if you put plastic or rubber plugs in them that were smooth and then covered the roof in vinyl? Shouldn't be any problems with that. When I took off one of my rails I am at a height I couldn't even see the bolt holes. If anybody else does this I would live to see it. ;D
