Welcome to the FGRV forum family. I never had to replace or fill in the seams on our 1st 13'
Scamp, but have read posts that you just fill the cracks with the caulking, and then use a damp wadded up paper towel to blot a texture that matches the wall, and after it all dries,
paint the walls & seams with latex
paint (be sure your walls are very clean for the
paint prep first).
