True deep cycle 12V batteries are NOT very common. Any battery that advertises a CCA or MCA rating is probably not a TRUE deep cycle battery, but instead a dual purpose "marine" battery.
He's right! The Cranking Amps gives it away. From gOOgle for this battery:
DC27 Deka 12 Volt 650 CCA/ 800 CA 175 Res/Cap Deep Cycle (Gr 27) Deka Marine Master Flooded Batteries. Deep Cycle/Starting – The Best of Both Worlds. High starting and deep cycle capability; Longer cycling than starting battery; Extra reserve power for accessory loads; Rugged vibration-resistant construction.
I don't know if Dual Purpose Batteries are as good for Starting as a pure Starting Battery, but Dual Purpose is NOT as good as Deep Cycle for applications like an RV "House" or a Trolling Motor.
Whether you need two or more batteries, depends on how you use the RV. We get by very well on one true Deep Cycle from Walmart but we don't boondock.
"The Best of Both Worlds.". Actually a compromise between both worlds.
