Technical Examples

A recreational vehicle (RV) with a central actuator that controls locking and unlocking of a plurality of access doors. Each of the access doors has a locking member that is interconnected to the central actuator. Thus, the central actuator may be configured to lock or unlock selected group of doors simultaneously. The central actuator is located inside the RV, and controlling input to the central actuator may be from a remote transmitter, or by direct manipulation of the central actuator. The locking members and the central actuator may be linked mechanically, electromagnetically, hydraulically, pneumatically, or in any number of ways. The central actuator advantageously permits an RV user to lock or unlock groups or all of the access doors simultaneously while inside the RV, or by using the remote transmitter.
