Actual UK price depends on the exchange rate. Basic price quoted for a Troll is 2049 Euros. This is for acrylic (tencate) material with a plastic roof - cotton is a bit cheaper. The depth would be 230cm (+ sloping front). They also do a 280 version. Extras such as windows in the front panel, a central zip for the front panel, a canopy over the side door, a sun canopy for the front, etc., are possible. The awning ends up pretty heavy. They charge 155 euros for a 'hefdak' caravan and you have to go to the workshop in Holland where they personally fit it to your caravan. You need to pay by bank transfer as they don't accept cards (unless from a Dutch bank). But the general opinion in Holland seems to be that Karstententen make the best awnings. Depends on whether you want a rather quirky, heavy but very well made awning and whether you are planning a trip to Holland! (NB I understand there are three lightweight poles that hold the roof out).
