Camco's retro RV level is a fun shaped, functional tool that helps show when your RV is level. Leveling your RV allows your doors and appliances to function properly. The level provides front to back or side to side leveling and can either be screw mounted or mounted with the provided double-sided foam tape. Includes two levels, so you can mount one on the back and one on the side of your RV. Patented.
