Dick,

Thanks for your response. The flex has probably always been there, and it's really no more than any of the other bits of the camper that sometimes flex when you walk on them. I had a minor crack last summer that was due to something falling and chipping, which I used the tub repair kit to fix. I placed a hygrometer under the tub so I can monitor the humidity, but so far it's been as dry as the rest of the camper.

Sometimes I just need someone here to tell me "don't worry about that, kid".
