mine was a pennine pathfinder, it only took 10 minutes to set up & was always cosy, you get charged the same as a caravan wherever you go, the ballache for me was having to leave site at 10am & then loosing the day as I wouldn’t like to leave the camper hooked up & go wandering off, so it was straight home. As well as having to open it out to air if happened to be raining when you packed up. If Europe has your fancy then a campervan is the way forward IMO, loads of cheap & free camping on the continent.
What swung it for me was that I found a 10 day all inclusive holiday, with flights & everything for £80 more than it would have cost me drive & camp for 7 nights.
We bought a caravan & sited it on a very basic site about 30 mins from cyb for the same cost as storing it for the year, pull up, put the kettle on & we’re settled in. We have a campervan too that is used to fulfil the wanderlust, we go to France, Spain, Portugal regularly in that & only ever pay for fuel, ferries & food, not paid for a site in a long time, here or abroad.
