With a GM truck the charge line is always powered from the truck to the trailer, so the solar should also keep the truck battery charged as well.
To avoid the trailer or camper from discharging my truck batteries (2 large expensive batteries!) I installed a relay that breaks the circuit from truck to trailer/camper. That way trailer/ camper won't drain the truck batteries and I can start the truck, always a good thing.
I would suggest either a relay or an isolator on the charge line after you figure out why the batteries went dead.
