I'm not sure about 8' wide vans, especially with sites (mostly CLs) which are located down what look like muddy footpaths. I've driven past campsites which was awkward solo, who knows how caravans got in there with oncoming traffic.
In my own experience, I've had to wait for an abandoned car, on the approach road to a site, to be removed by the police; otherwise I would have had to put the offside (the side with 4 windows) through a hedge and dodge a telegraph pole to sneak past - probably not possible with an 8-footer. Hilariously, whilst waiting, a person who decided to not wait, rode past on a bike and moaned to the Cop that he'd scratched the windows on his new van on the hedge.
