I’ve been wanting to permanently mount a solar panel on the roof of our truck camper since installing the Truckfridge TF49 compressor type refrigerator. Routing the wires in was the biggest obstacle. Through a few internet searches, I decided on a marine bulkhead. I used 3M 5200 to seal this little guy to the roof, then routed the wiring through the tent and cabinets and down to the battery.
