Bailey Unicorn Series 3 - Damp

I have a U3 suffering from that problem. The outer cloaking covers are just for appearance the main skin that runs from the roof goes behind the cloaking panels to the floor underside.

On mine the the polyester outer skin falls Just short of the floor underside so water tracks into the plywood and Eventually rots the floor.

Not all vans are the same I've checked other U3s where the outer skin runs below the floor and water drips clear away from the floor. 

Daft question, but why buy it if it has damp? If it has got in once then it could get in again and I'm guessing it can only be 6 or 7 years old.

Avoid it, as those above advise, you’re buying trouble that’s probably overpriced as well given current market demands for new and second hand vans. 

We have had similar problems with our 2010 Pegasus. All the front, side and  rear trims were removed and the joint between the walls and floor sealed and new trims fitted. It seems quite a common problem. Every year I now treat the underside of the floor with a liquid wood preserver which I spray on, paying particular attention to the joint between the walls and floor. As previously  said by others I think I would look for another caravan
