We have a caravan, and we add a porch awning (rather than the large awnings) for more room, and also we put down a groundsheet, its a breathable type, so, depending on what campsite we go on, it goes down on either gravel or grass. If on grass, then the grass grows through it without making it go yellow. We don't usually go out during winter, being in England and depending where you go, its either dry, wet or icy and always cold, but a lot of people decorate their units during the Christmas holiday and sometimes halloween. Looks lovely. Have promised myself that one year, we would travel up to Edinburgh for the hogmany (to celebrate the new year). People always have a great time up there, but as you guys will know, the further north you go, the colder it becomes
