I’m about to go on a trip in Europe for the next few months and thought it would be a good idea to buy a camper to live in during the journey. However, if I buy a camper van I must use that as transport in cities as well. If I buy a trailer I can always unhook and use the car while my trailer is parked.
I’ve visited lots of European cities with a small campervan, and a large one.
I would either park at a camp site, or close to the city and then take public transport, or cycle to the city centres.
Parking a campervan (that isn’t too big) is not much of a problem in most European cities. Just don’t get too close to the centre.
A campervan allows you to camp at places like quiet beaches and Aires, where as a caravan/trailer requires you to always go to a campsite.
