Caz,
That is a whole shxx-load of signs that say NOT!
I like the idea of a middle-eastern carpet in the van.
Benignly, visions of Scooby-Doo and friends.
More risqué would be my imaginations of...well..."love mobiles"
That's a staycation I can empathise with.
Most likely, it's banned on one of the signs posted in the so-called recreational park.....
Regards,
MTF
