I think I recall something where people who had done up campers / caravans oldish/newish not sure could pay someone money for a pitch somewhere so they could all meet up. Remember hearing about it on a forum in last couple of years. Don't know if it involved a bit of music entertainment as well.
Still not found anything,only van life uk on youtube which is just some couple living in a van and in my view pretty tedious viewing. Vanlife magazine and vanclan.
To be honest id rather keep my money in my own pocket than pay to finance someone elses lifestyle and travel adventures because thats all theyre running these sites for is to provide themselves with an income to finanxe their lifestyle.
Only other forum im on is wildcamping and you get a database of parkups for the membership which is the only reason i joined many years ago. Ive no interest in the motorhome or campervan scene personally because it seems heavily populated by people i wouldnt associate with in a million years.
Ill keep looking though,if i find anything ill post it here.
