For what it's worth, I grew up driving a K5 (V10) Burb and drive a Yukon XL daily now. Yeah, it's longer, but I park it everywhere I go, including parallel parking downtown. My buddy's '14 extra cab short bed Silverado is longer, believe it or not, and has a much worse turning radius. I thought with the IFS, the radius on the Yukon was going to be worse than I was used to, but I can stick it about anywhere. If I can't, then I probably not wanted there!
