Strongly recommend 6 Volt Deep Cycle Golf Cart batteries for House bank - it takes 2 6V to replace each 12V, but definitely worth it. I also recommend going with AGM as they are maintenance free and tolerate vibrations better; however, charging profile is slightly different so you may have to replace chassis battery with AGM (12V) as well. Expensive proposition until you factor in longevity and power availability advantages. Also adds more weight.
