First question: What is your purpose in splitting the battery banks?
I don't see what type of RV you have. If it's a MH, putting the starting battery in a separate bank makes sense in case you run down the house bank, you can still start the motor.
If it's a towable or you are splitting the house bank on a MH, a single large bank with a low voltage cut off has some significant advantages:
- You can charge at a higher rate (without complex combiner systems)
- Puerket effect is less of an issue since you are effectively halving the draw as a percent of amp-hr, so you effectively can pull more amp-hr out of the bank.
- There are fewer parts to fail.
