I decided to work on the front of the caravan now that the floor in the rear is fixed, I haven't repanelled the rear yet as I'll do that once I've finished the front as it gives me somewhere to store the furniture from the front.

The furniture came out more or less in one piece, some of the glue has perished over the years and also some of the smaller support timbers have rotted where they have been in contact with the damp so I'll replace those and also glue them when I reinstall them.

You can see from the photo that the right had side has suffered the worst, it appears that a repair has been made in the past, but as the leak wasn't fixed it just rotted the repair, also the repair that was done to the floor was done incorrectly, they had use wood between the upper and lower pieces of plywood. The foam is there for three reasons, the main reason is its lighter than wood, it also acts as insulation and finally it acts as a vapour barrier stopping water bridging the two layers of ply.

Below is a diagram showing the floor construction


Looking at the water stains on the ply I suspect one of the windows is leaking. I'm going to fix all the interior problems before resealing the roof and rails, the reason I've decided to do it this way is because the support timbers have rotted and I don't want the structure to fail,
