Agree with previous post, this is very bad advice and the info is wrong. Going with a dual purpose battery is like taking a knife to a gun fight. It will get you from home to a CG where you plug in again, but has very little actual long term capacity and will have a much shorter life if used on an RV where occasional drawl down and recharge are a factor. The only advantage is cost, as dual purpose are generally cheaper to purchase and you can stick it in your tow vehicle in a pinch.
Get a true deep cycle.
