I bought a 2014 Trillium
from Great West Vans (dealer in Bay Area of Ca). Moved cross country to NY - first rain flooded inside of trailer. No help from dealer. Discovered hole the size of my pinky finger in roof where solar
wire feeds in. Wire has flimsy plastic sheath around it - hole is a bare hole that just looks drilled into the fiberglass. (In a water run-off trough no less)! Obviously they forgot to add something and overall seems like poor planning. I am wondering how to fix this. Can I seal with Dicor around the wire?
