Just speaking for myself, every hole is a potential future leak, and in the roof, more so. I would do all I could to limit roof penetrations. And on a rig that had wood structure underneath the
fiberglass (doesn't the Bigfoot have some wood in the ceiling), additional concerns.
Most the threads I have read on restorations, if anything was done on
fiberglass roof or wall penetrations, it was fiberglassing over them.
