hi not sure wher you will get wallpaper as i have the same problem as you but i would just like to say the previous remark on sealant is not the rite way to seal the seams there is a special sealant for the caravans that never sets but you have to thke the trim and awning rail of and clean the old selant of with white spirit and it is recomendt to use a screw a size larger than the one you thke out and again you can clean of the excess with white spirt
