Hugely disappointed to find significant damp in the wall of the comanche behind the driver. Did have a report of damp a couple of years ago which the dealer said was the window so that was repaired. Next service was done at the Motorhome Depot near Birmingham and no damp found but they didn't look under any bench seats etc so missed it. Report this year is damp with soft internal panel so urgent repair now being done. Seems the AT construction is that the side walls sit in a metal trough and this fills with water running down the walls if the seal at the bottom of the wall behind the grey plastic trim is not very good and ours clearly isn't! I have read that AT give a 10 year warranty against water ingress? Has anyone tried to claim on this and if so how? I think most AT's could suffer from this issue so I would make sure that your damp check includes anywhere along the bottom walls of the van. Pictures to follow.
