The Weisshorn 18–20ft Caravan Cover is built for serious all-weather protection, featuring a heavy-duty 4-layer polypropylene construction that blocks UV radiation, resists water penetration, and allows moisture vapour to breathe out — preventing the mould and condensation that can quietly wreak havoc on your van between trips. Engineered to fit caravans and campervans from 18 to 20 feet, the cover sits snugly over your rig thanks to reinforced elasticated hems and adjustable tie-down straps, holding firm even when Australian winds do their worst.

Whether you're storing your caravan between outback adventures, keeping your pop-top protected on the driveway over a Queensland summer, or shielding your motorhome from the dust and UV of a long NSW dry season, this cover does the heavy lifting. It's the practical choice for 4WD tourers, grey nomads, and weekend caravanners alike who want their investment protected year-round without the hassle of a dedicated undercover garage. Comes with a compact carry bag for easy off-season storage.

Common questions about 18-20ft Caravan Cover Campervan 4 Layer UV Water Resistant

Do the tie-down straps really matter?

They are the difference between a cover that lasts and one that shreds. The elastic hems hold the shape; the adjustable straps underneath stop the whole thing lifting and slapping once the wind gets up. Tension them when you fit it, then go back and tension them again after the first windy night.

Can I leave it on for months at a time?

That is what it is built for, but look underneath now and then. Lift a corner every few weeks, check the corners and mouldings for rub marks, and make sure nothing has pooled or crept in. Long-term storage goes wrong slowly and quietly, not all at once in a storm.

Will it fit a pop-top?

Yes, as long as the van measures 18 to 20 ft. Fit it with the roof down, because raising a pop-top under a cover loads seams that were never designed for it. Hatches, aerials and solar panel edges do the real damage, so pad those before the fabric goes over them.
