Hello friends, I have a question. I did extensive touring/overlanding in Australia. I always used a Swag (which is a small one man tent) and/or an Oztent which is big tent easy to put up. I moved to Europe and shipped the car and I am planning to do some overlanding in Europe soon. I see here in Europe Rooftop tents are very popular. Is there a special reason why? Is because of wildlife? Is it safe to sleep overnight in a normal tent on the ground? Many thanks for you input. Ossi
