Joe, I don't know the layout of your caravan, so perhaps this is completely irrelevant, but I wonder if you share the problem we have of a door at the front of the van which makes it virtually impossible to fit a porch awning of any description? After looking at every option, we decided to buy the Scenic Plus. This will not fit over the door, but then nothing other than a full awning would, so we have to forgo the benefit of a true porch. However, by fitting it on the straight stretch of rail beside the door, we have at least gained useful space in which to sit and eat when the weather is less than perfect. It also provides us with somewhere to keep chairs and other bits and pieces dry overnight or when we are out during the day time.
We have been impressed with the performance of the Scenic Plus. It appears well made, is quick to put up and take down, lightweight and packs down into a small kit bag for travel. So despite the fact that it is not the perfect solution, we feel it has enhanced our enjoyment of our caravan.
