I don't have my own travel trailer yet. But in the future, I want to buy one, and I'm also interested in the question of which one is better to take. In the meantime, I rent cars and travel by them. I have a pretty big family, and we rent multi-seater cars. When we were in Edinburgh we rented a 7-seater minibus here https://rental24.co.uk/uk/edinburgh-airport/7-seater and it really suits our family because we are comfortable and it fits all our luggage perfectly
