Hi, Just need a bit of advice please. Going on our first trip next weekend and wanted to check what I need for connecting to fresh water? What type of connectors do they have on the taps at sites? Also, are any water carrying containers essential (fresh or grey) or will all sites have a place where we can park next to a tap? Thanks Martin PS. Also should I carry two lengths for my hook-up as the one they supplied with me HM was 30 metres which appears way too long !! Is it worth having half that and then if I need 30m i can connect them together to make it up to 30m again?
