I think you need to get out more I’m a lone traveler aged 74 and do everything with my van, including emptying the loo.Granted, Men are completely useless at loading and operating washing machines, whereas women are hopeless at loading dishwashers correctly... however, as SWMBO pointed out this weekend, why is it only the men who empty toilet cassettes....? This got me thinking and has played on my mind since..........In all the years of people watching on sites, I have never witnessed women emptying a cassette... we know there are lady only campers out there - perhaps they wait till dark or go in disguise....
