Caravan Pre Wallpapered Wallboards

Hi

Does anyone know as to where we can obtain pre wallpapered wallboards for our 2005 Bailey Pageant Champagne as we have a little damp in the en suite area that needs to be rectified.

I vaguely remember there being a company around the Manchester area that done it already on the boarding or you could purchase it on the roll.

We are in the Wigan area so anywhere reasonably close would be great but we would travel or have it sent out.

Any info or links to companies would be greatly appreciated.

Regards

Tony
