Do I need caravan insurance, and roughly what does it cost?

Your car insurance generally covers your legal liability for damage the van causes to other people or property while you're towing — but it usually does NOT cover damage to your own van, theft, storm or contents. For that you want a dedicated caravan policy. Cost varies a lot with the van's value, where it's stored and your cover level, but many everyday vans land somewhere from a few hundred to low four figures a year. Look at whether it covers you in storage, annexe and contents, new-for-old on newer vans, and off-road or interstate travel. Read what's excluded — that's where the surprises live.
