interior panel or exterior panel?
Exterior, usually just remove four screws, one in each corner, then work the cover off. Sometimes there is a tube within a tube that needs to be slid out.
Interior, you'll have to wait for someone familiar with that particular RV. There's usually not much that can be accessed from the inside. Most components are accessed from the outside.
When seconds count, the police are only minutes away.
