I am building a truck slide-in camper (Glen-L "Importer" design) and
am using epoxy for most things thickened with fibers and balloons.
However, in places where I think there will be less stress on the
camper inside, I am using the cheaper and easier to use "Tightbond"
waterproof glue with all joints screwed together. For example, I am
using the Tightbond on the cabinets. How does this compare to epoxy?
