We came across these at an Island Wanderers meeting at Sidmouth just after the CMCA 2004 Tasmanian Rally. Jan and Ed from the CMCA Central Coast Wanderers have simply placed a cheap suction hook from any old knick knack shop such as Chicken Feed in Tasmania and placed it near the front door lock. They come in packets of two and cost about $3.00. To remove you simply lift up the lever and you get instant release. Jan also hangs her broom on it when on site for a few days. This stops the paint damage you can get if you leave anything leaning up against your motorhome.
