100th admission Hobby 440 SFE 1998

Hello Community , I have a question for the 100 he registration of my caravan. I want to get TÜV next year and get a 100er report only which conditions I need for it!? I know so far only that my tires are not allowed to be older than 6 years. But what else do I need !? Shock absorbers !? Does my caravan !? And what else !? Do you happen to know this or do you have an idea where I get a list of what I still have to do!?
