For me it is a caravan every time. Yes, they are intimidating to tow to start with but soon enough it becomes easy, especially if you learn how to reverse. You get heaps more room, proper washroom, fixed beds. You have to adapt your mindset - when you are towing you are moving from a to b along the easiest roads you can find, and expect to spend the day disassembling and reassembling everything including the awning. But once you are set up you have a comfortable base and the freedom of your own car.
