Install Rating (3rd Party Work 10 = Best, 1 = Worse)
Additional external lock to prevent easy forced access via the none standard wide accommodation door. The lock prevents both top and bottom halves of a stable door from being opened. This lock can now be bought much cheaper since I installed mine.
Holes are required to be drilled through the motorhome wall to securely bolt the lock to the outside wall of the motorhome. Some internal cutting and filing was also required to produce a neat job.
