Suggest you read up on unbalanced wiring and understand why those long wires from the truck have voltage drop especially at higher loads and charging and is part of the reason for your results. Battery amps will not split evenly (with 3 equivalent batteries) due to your unbalanced battery wiring.

My set up is only for when parked at camp. Truck will be plugged in during PM hours.
A quick start of truck for 30 minutes or so to get some amps in the batts in AM and let solar continue from there.
This has the real potential to wake up with 3 dead batteries and the truck won't start.
