Adco™ Pop-Top Cover, suit 5.51m-6.12m (18ft - 20ft) The ADCO Covers come with three years warranty to provide a more durable alternative. With a four layer Dupont Tyvek top panel it is far more durable than similar covers in this price bracket. The top material also is wide enough to go beyond the top and over the edge where most wear occurs. These covers are imported by Coast to Coast. What size? Measure the total length of the outside of the Caravan, at its longest point, but exclude rear bumper or rear mounted spare wheel. Roof top air conditioner makes no difference as the walls can be pulled down to suit. The front is sloped as per normal modern caravans, so alternate shapes may not fit correctly. These should be kept snug on the caravan to prevent billowing in the wind and constant rubbing on corners which will otherwise wear a hole in the Fabric. Features Designed for high sun exposure, high moisture, snow and/or long term storage.
