Part of our Tried-On Awning Range this exceptional Approved Used Vango Tuscany Pro Air 400 purchased new in July 2026 and only ever erected once on a hard-standing pitch. Following incorrect fitment advice from another retailer, our customer discovered the Tuscany Pro Air 400 was unsuitable for their vehicle and subsequently traded it against a perfectly fitting Westfield Vega 375. As a result, this awning has seen virtually no real-world use, with many accessories and removable panels still remaining in their original packaging.
