You asked what YOU NEED: that can only be answered by YOU.
Your coach needs 12 volts worth of batteries between the positive and negative DC busses. I told you where to get the most bang for your buck to meet that requirement. I don't know of anyone that has chosen a Universal Battery replacement like the one you found on Amazon but if that's what you want to buy, it MAY work if your charger/converter can match the required charging profile shown on the side of that battery.
