We done if for a few years before buying a static, great fun!
Join the camping and caravan club with hundreds of sites including Europe if you brave enough.
We enjoyed the CL sites also, usually a farmers field with only a handful of other caravans, peace and quiet and lovely walks.
Couple of nice sites Bakewell Derbyshire , one in a forest you will find in the book.
Went to Paignton Torquay a few times, lovely down there although a bit of a drive, we would set off after rush hour and park up at Worcestershire Services overnight £10 with a breakfast voucher before continue the journey after the morning rush hour.
There is also a nice site in Blackpool we stayed at if we were going to see the lights.
You may want to consider breakdown cover , Green Flag Is the go to one for Caravans iirc.
Invest in a decent Awning and Tow bar locks and a wheel clamp!
I could go on all day!
PM me if you need any advice.
Happy caravaning!
