Over the last few days I have been tearing apart the front nose of the camper becuase of a small leak near the front drip rail...I noticed a bunch of carpenter ants in the front near the rotted wood. ...
They will likely go away once you get rid of the wet wood, especially if you store it with no food or water in it. Carpenter ants are hard to kill, they do not go for ant bait. I had them in my house. Chances are the one sin you trailer are a sub colony. Do you have lots of trees aroudn where you park it?
