The Thomson caravan is not the cheapest on the market, and you can see why if you walk down the production line and look under the skin.
The fundamental feature is its "bone structure," the genuine hardwood framing of Malayan Meranti, braced where required by aluminium ties. Hardwood is not only strong and rigid, but it repels damp, is less likely to warp and rot than softer timbers.
The skin is important too. For the outside Thomson uses a heavier gauge of aluminium than most manufacturers, and inside is laid a one-inch thick blanket of mineral wool, before the inner skin is applied. The roof is lined with hardboard because it is easier to shape, the walls panelled in veneered plywood. This is more costly, but besides being aestheti­cally pleasing, it is more durable and lighter in weight.
While walls, end panels and roof are assembled on precision jigs, the building of the caravan starts from the ground up. First with the B. & B. steel chassis, and the Beta hydraulic coupling, which together are the basis of the excellent towing qualities of the T-Line caravan.

All of which means that the Top Gear method of curing caravan damp/rot will work all the more effectively

Whats that on about???

On the damp issue, firstly buy yourself alot of SALT and place this in several plastic containers around the caravan, this will firstly draw all the dampness out of the air, next if money is available hire a de-humidifier and leave in the van for a day or two and dry it out fully.

Then find where the damp patch was and look on the outside edge, this is usually below a seam, run a bead of clear silicon over top and bottom and try and seal that joint.

Hmmm, not cheap.  About 4 gallons of petrol and a box of swan vestas....

Just the one would do, surely? That would take out the whole site.... Actually - yes, 4 gallons, that's right.

Something like this, perhaps.

Then again, I hesitate to post his suggestion for a Rover with HGF.

Yes, I'd give it to the pikeys to avoid those costs, then buy a nice new up-to-date van!

wheres the damp and how bad..if the boards soft then they need ripping out to dry the timbers,window ruubers leak/mouldings leak/panels crack,never pressure wash a caravan and clear silicone is only a temp bodge there is better things out there which can perform a longer lasting (bodge)repair one is called geobond which comes in a tube like silicone but its all down to how much you like  yer van and if you want it fixing right cos that does involve boards out/heat on/dehumidifier on/leaking joint resealed/new board/adhesive and depending how wet it is it can take a good few days just to dry the timbers

Looks like it came in through a small crack in the front panel. Damp is restricted to a smallish area so will cut out. Got Sikaflex already.
