Door Handles & Locks...

Here we see a close up of the RV-quality door latches. Each has 2 locks, a "handle lock" and a "dead bolt". For added security and peace-of-mind, both locks can be operated from inside your trailer. The rocker switch in the upper left corner of the picture is the optional external "master" light switch... it can turn on / off all your interior lights before you ever step into your trailer.
