Rodney alone on planet

I'm looking for the story where Rodney gets culled (?) but manages to escape, and his GDO is disabled somehow, so he leaves it at the base of the gate on the planet he winds up on, which is empty (culled).  After many months Teyla, John, Ronon and Radek arrive to trade with the previous inhabitants and find it...

I'm pretty sure this was on wraithbait, and I've been searching but I've not had any luck and was hoping someone here could help me.

Cheers
