Desktop TruSkin - Can be flighted from top ad slot - could be a leaderboard or billboard.
Mobile TruSkin - If the sites have a sticky ad then request you to flight it from there, else it can be flighted from the MREC.

Tablet: Leaderboard (728x90), Billboard and Horizontal Middle Page Unit (MPU)
Mobile: MREC and Middle Page Unit (MPU)
