It's not an AU, so it won't fit on my recs page, but Running on Empty by Sholio is a great gen action-adventure story. It's Sheppard and McKay centric, about 89,300 words long.
I just came over here after the comment in my LJ to look at your userpics (which are too cute -- I love them!) and happened to notice that you'd recc'd my story -- thank you! :)
