I've seen the same map now in several games:

Top (Opponent):

Woods on their right, large gentle open hill just in front of their camp.

Bottom (Mine always):

Hill on left sort of middle of map...i think one way back at back edge.

But I'm always on the same map side. My opponent every time has had the centre hill just in front of his camp.

Is this just weird luck or is there a system to the maps and who's on which side?

I have maybe played the DAG a half dozen times and have had different maps each time but have used different settings for how crowded the map would be.
