Agree with you re the rows of white boxes , not really sure what a whooshbang is ?
When I first started was a little nervous about where I parked . Then discovered the freedom of wild (rural and urban) camping . Decided not to ever use campsites etc . Now , with more experience , I use campsites very occasionally . Never got round to joining any of the clubs .
That is what suits me , fortunately we are all different .
