My beloved campervan had damp around the window frame. After investigating how much it cost to have it repaired professionally, I decided to fix it myself. See the results and method here.
Parts were purchased from O’ Leary Motorhomes – http://www.olearymotorhomes.co.uk/
Hope it can be of some help as I found no resources on the INTERWEBENZ.
