Hi there,our first winter and need some fairly swift advice on protecting our motorhome over the winter when it's sat on the drive and a frost hits. We are using it almost every weekend but it's just. Oat £100 to replace a tap and don't want to make that mist are again. So advice on draining down etc between uses over the winter would be appreciated. Hubby outside as we speak as brought it back today and almost forgot again
