Over the years I have seen Items made for the caravan which I am sure must have been designed by some one who was not a caravanner.
The one I nominate is the combined fresh water and waste water carrier, the idea was the container had two strong plastic bags in side when you filled the fresh water bag it forced out the waste water from the other bag. The problem was that on most sites the waste water disposal point is not at the freshwater tap for health reasons, the next fault was that any hot waste water transfered the heat to the fresh water making a glass of freshwater warm yak.
Any one got other examples or did you have one and are you still using it.
