I'm currently looking for a van for my folks, just because I've been vanning for a around 3 years now and my parents have been out of it for 20 odd years they want me to choose and check over any van that I think will be suitable, I've found them a lovely van which seems to tick all the boxes, but it's had damp in the past, would this stop you from buying it or is it considered once treated then it's all ok?
