Dave and Karen (away in France at the moment) have discovered a very good way to secure the sliding side window, the one by the habitation door .
Some of you may have the steel tubular frame that holds the armrest cushion and drops into the brackets on the settee bases, just behind the front seats. They use one of these frames to drop into the window frame and block the forcing open of the side sliding window.
Well-spotted, Dave & Karen! A good use for this armrest.
