Hello, I’m about to buy a caravan from Denmark. It’s super in stand and the price is great. Unfortunately, the previous owners were afraid of gas and didn’t use gas in the caravan for 10 years, neither for heating nor for cooking. So you can’t guarantee whether it works. Do you have experience like it is after 10 years? Do we have to completely renew everything? And how are the costs for it? Gas testing and TÜV we have to make a new one here in Deuschland anyway.
