I really dont know if I should be adding more fuel to this debate,but here goes anyway.I have driven many miles in europe and the UK with my 2.5 wide caravan and have never had a problem with entrances to sites even though I am a massive 6ins wider,And regularly reversed into my standard 10 ft wide driveway,used normal pitches erected a 3 meter in depth awning and still maintained the 6 meters between caravans stipulated by both clubs and reputable commercial sites,although they are few and far between these days.Although the roads in england are in a disgusting state of repair,the worst in europe apart from Romania maybe,Im glad of the shockabsorbers that are fitted as standard and the increased stabiliy they give especially when being passed by HGVs on german and dutch m/ways.
Narrow roads are narrow roads in any country and I think it rather foolish to think the UK has the monopoly on them.The uk caravan industry is already going the way of the motorcycle and car industry as more and more brits look to europe for a better built and better quality and more for your money.
I have never been and do not know of anybody who has been stopped by the police or the MOT inspectors for threr caravan being to wide,but maybe someone has ?????
