Drill collar, there are lines, pipes, and wires in the walls. Put a bottle jack under the structure just at the rear of the front slide. Raise jack until holes realign. Look closely at juncture of slide opening to coach to ensure it has not puckered or pulled away. Thats a water intrusion issue if it has.

3M adhesive remover dribbled into the adhesive tape will help it come loose. I guess that was a later repair by a previous owner.
