[Colne-camping]

I'm hoping someone can give me some helpful advice. I've recently bought a 2006 California ocean, and after the heavy snow we had, I went to check on it.

I was welcome with water in the footwell and dampness everywhere.

I've had a dehumidifier in there all week and now managed to get the time to get the roof up and see if I can spot anything.

What I've found is, the canvas has come away in the corner on the seal, and I've black mould in the roof liner.

Does anyone know how to fix it, and get rid of the mould stains. I've white vinegar, and wet vac the roof liner.

It's annoying, because I thought I prepared it for the weather by cleaning all the drains out, that didn't actually work.

Thanks
