I did the same thing. Added 4ga 100amp charging circuit to my truck to the batts. I can't say what's in yours, but what I did was drill a very small 1/8" "exploratory" hole to see if the bit hit anything.
In my case I could see from inside the camper I wouldn't hit wires or plumbing, and like you said, all I hit was Styrofoam and fiberglass.
**Make sure you run an automotive 100a or 80a circuit breaker on each end of your 4ga.**
If the wire gets snagged and shorts, the camper batts can start a fire just as easy as the truck batts. Putting breakers at each end will prevent it. Plus it makes it easy to just hit the disconnect on the breaker when you're parked to separate truck from TC batts.
