Got alde system and a 300 page hymer manual plus several other manuals . Some of the suggestions are really OTT .... Maybe this is because it is designed for Germany and places even colder . It says take out TVs , completely empty all upholstery, any other loose fixtures and fittings including gas bottles whether empty or not! We don't live in a mansion with several spare rooms and the ones we have are already full of junk ( says he!) We can leave it on hook up but is that an unnecessary expense? Any help gratefully received.
