One is your starting battery and that should remain. It is dedicated to the engine. The other battery is your "house" battery and a deep cycle battery will tolerate the discharging and recharging better than a starting battery. However, both will work. In fact, if you do little boondocking, you won't notice the difference, so just wait until the house battery fails and needs replacement. Now, if you have two house batteries and both are starting batteries, when it comes time to replace them you should consider two 6 volt deep cycle batteries. Those 6 volt batteries tolerate the charge/discharge cycles better than their 12 volt counterparts due to the size of the cells.
