Just to let you know I now have van back and the garage have not sorted the problem. They had the van for 2 weeks, said they stripped it down and the only thing they could find was the leaves. They could not find a leakage anywhere else. I got them to dry it all out so I would know if the problem was cured or not and hey presto just as I suspected as soon as it rained there was damp in there again. I don't understand how it can be getting in there. The only thing I can think is that is must be coming up from underneath. Do you think that is possible? Also how long can you sustain a wet floor like that before the whole thing rusts through? The garage said it is an old van as if it is something I should just put up with, but it's not that old it's 2003. I've had much older vehicles than that before. Do you think there is anything I can do or do I just have to accept defeat. If the vauxhall garage can't find the leak then I doubt if any other garage will be able to. What do you think?
