I'm with RAA for the vehicle and camper. As long as I'm legally allowed to be there and drivig with due care I'm covered. So if they found I was being an idiot doing donuts with the camper (how I don't know) and rolled the lot, I'd be without insurance. I saved hard to get my gear though, so that isn't going to be an issue.
They are super easy to deal with in the event of a claim, free windscreen per year, no claim bonus for life etc. I've tried a few others, but I keep coming back.
