Thank you! Yes, very old (1993) and has been sitting for over 10 years. We wanted the location- so just kept the trailer as it’s not movable as-is. We figured we would replace it if it wasn’t worth keeping. Impeccable inside except for this carpet and debris under the window. The weird thing is there is no visible water damage on the walls (it’s wallpapered) that I can see, and the carpet wasn’t mushy, just felt damp. I just don’t feel comfortable in it, especially as mentioned on this thread, there could be mold! Should I get an RV tech to inspect it inside and outside? How would I find one? It’s in Julian, CA.
