Tailor made front towing cover from Specialised covers. It's to fit a Sterling, Swift, Sprite caravan. Mine is a swift fairway 584 2014 model. As long as the lights are in the same position as mine it will fit the above models (Photo enclosed)
Fantastic protection and very easy to put on. Has a zip one side and elasticated wings.
In my opinion these are the best towing covers on the market, lovely soft material that is almost like a thin foam.
