You have thrown out a lot of questions with different variables, so lets try and figure some of it out... You tell us a 30 amp park service and inverter off, NO, your batteries won't run down if you are only using 120 Volt loads. If you exceed 30 amps of 120 Volt draw, you will trip a breaker.

Now, if you have a good inverter that will share load, and you draw more than the 120 Volt current limit setting, say 30 in your case, the inverter will draw 24 Volt current from the batteries and make 120 Volt AC out of it and add it to the 30 out of the shore power.

Remember that 10 amps of 120 V equals 50 amps of 24 V with a perfect inverter, which doesn't exist. So 10 Amps of 120 V = about 55 amps of 24 V.
