We have our new caravan in storage, but unfortunately the warden has placed us under a tree, and says we are lucky to have the storage facility. We read in the magazine that when travelling some people put clingfilm over the front of the van to keep flies away.... we were wondering whether we could put cling film over the front of the van for a couple of weeks at a time, so as it is easier to clean the van from bird droppings. We were going to buy a cover, but have heard so many disasters!!! ANY ADVICE much appreciated...please. barbara
