Hi. Bought my first motorhome last year and had great difficulty finding somewhere to store it within an hour south of London. Found a site at last and it has been stuck under a forest of deciduous trees for 5 months. I desperately need to get it cleaned but can't find anywhere around Dorking. I'm looking ideally for a specific motorhome wash station as I understand I shouldn't use jet sprayers at a normal car wash. I'm happy to have a mobile valet but do they come with water as there is no access to this at the site. Help?
