I've just had a classic fitted to my new van, it works really well however it takes quite an effort to manually engage the rollers due to a combination of the high pressure caravan tyres and the newness of the unit , if your physically fit it's ok, if not go for the auto engage model.
I must admit we went for the evolution mainly because we have to watch our van weight & it was lighter.
