Oh man, a traveling snake. Yuk.
I must say, I never ran into one of them in a camper before, yet anyway.
I have run into and hit an active large black ant situation. Some variety in the carpenter any family. That was bad, the rear wall was wet and they were thriving in there. They seems to like to nest near the 120 VAC electrical outlets. Something about flowing current in a wire, ants are attracted to.
Every piece of insulation I pulled out I had to watch carefully I did not have visitors come with it. Went through many cans of ant spray on that camper.
Good luck with your camper repair. Would be great to see some of your project. Consider making a post in the Repairs and Maintenance forum. We all always learn something from repairs like this.
