“First spring in four years I didn't find damage.”
Travel trailer stored November through April. I spray-foamed every gap before storage for three seasons straight—and still found damage every spring.
The damage was never at the entry points I sealed. It was behind the furnace and in the wiring along the rear cabin. I couldn't figure out how anything was getting in.
I placed six Fugelyn pouches before this lockup. Opened in April. Nothing. Not a dropping. Not a chewed wire. Not a smell. The sealing didn't change. Fugelyn was the difference.
