thanks for the information- we'll certainly think about using it next year. Campsites are expensive in Italy costing around 30 euros a night so you'd get your money back, but this year, en route to Greece, it was more expensive to stay in a service station as two Italians decided they'd like the contents of our front passenger side pocket and broke in to do it. They got nothing apart from a nightwear-less English woman screaming at them....I hope I caused them serious psychological damage! ( the services were well lit, plenty of motorhomes and caravans there but we didn't take all our usual precautions- used curtains instead of blinds, didn't put the ratchet strap on between the doors.....the services in question were Castel Santo Pierro Therme...too close to Bologna in hindsight) Well you learn from experience....:-(
