Denali and yukon are the same thing, in fact the denali(47k-53k) is just a decked out yukon(36k-41k)... the line goes Yukon, yukon xl, yukon denali, then there is a yukon hybrid,

I think we both know that! Denali is a higher version of the Yukon.. just like Escalade is a higher version of the Suburban. I just wondered if it was a denali because the pic she posted had the chrome handles and I thought it said denali on the side.
