RV portholes are windows installed on the top or side of the camper to provide natural light and ventilation. They can also be used as emergency escape routes in case of emergencies.

There are several camper porthole options available, including:

Hinged portholes : These are opened and closed manually using a handle.

Sliding portholes : they are opened and closed manually by sliding the porthole along a track.

Retractable portholes : they are mounted on a track and disappear completely when closed.

Roof lights : These are mounted on the roof of the camper and can be opened and closed manually or electrically.

RV portholes are available in various sizes and materials, such as polycarbonate or glass, and can be permanently installed or removable. It's important to choose a good-quality porthole and ensure it's properly installed to ensure good ventilation and weather protection.
