The canopy/awning was available in a lot of sizes. Specific models would fit higher and lower awning rail heights of Familia, Triton and Troll. I think they also did models to fit my Feeling and other pop-top caravans. The Caravan Canopy Shop, who I believe have now thrown in the towel, used to sell the canopy and it was a favourite of theirs. https://www.caravancanopyshop.co.uk/ Because the range of sizes offered was considerable and yet the potential market comparatively small, especially when you add in the different front and end panels, Wigo ceased production of the product. This really is a shame as when just used as a canopy it looked wonderful.
