Battery bank tip - Be sure to include the entire bank in charging and using. Hook up the charge method - ie generator, solar, wind - "in" (+) to one terminal at the first battery in the bank and the "out" (-) to the other (terminal) end of the bank and then hook the usage ( ie, inverter, coach, etc) the opposite way. Also, be sure to properly ground the bank to the chassis of your RV. Use a large size wire for the ground, perhaps #2 or #4. I assume that everyone will use fused blocks at both ends + and - for safety. I use 160 amp. fuses in case of a major problem Got these at AutoZone.
