You seem to have taken a wrong turn at some point while driving towards Dunekicker Base Camp. Even worse, your camper trailer somehow got loose and fell over. After checking your map, you realize you're still not clever enough to figure out a route, but you're sure you got the general direction right. Soon an important event that you don't want to miss will happen at the camp, so better hurry! Flip over the camper and get going!
You've completed your duty of loading your trailer with abandoned junk. Now, make your way back to the highway and deliver it to the settlement. Be patient; you may need to drive very slowly in some sections!
