Hi there, i"m Kelly from Vancouver bc. I just purchased a used 17' 1982 Bigfoot
trailer. I love it except for one little problem, on the ceiling, beside the vent there is a slight sag and when I touch it, it feels colder to the touch and thinner, like someone had repaired it. On closer inspection, I realize that it wust have bee a recent patch job because the more I played with it, the recent paint
began to crack and now I'm really worried that its bad. I've looked everywhere on line to find information about this but have come up with nothing. I'm hoping someone here can help? How do I fix it? Thanks in advance.
