First Time Boondocking Plan - Tech Question

First of all, THAKS EVERYONE! Guess what: I think I have been making a mistake wrt my battery and shore power setup. There is a switch next to my front/rear jack switches. It is to disconnect the batteries. I have been disconnecting the batteries whenever I am on shore power, then reconnecting for moving between sites. I guess this means that my batteries have not been charging up and staying charged. (this may be why one of my slides seems to run very slow lately). Anyway, the voltage across the batteries with the switch off was 11.9-12.0v. I just switched the batteries on and the voltage across the batteries went from 11.9-12.0v and is on the way up to 13.7-13.8v. My power converter is an Inteli-Power 9100 Series, possibly a 30amp (I am trying to get to the model number on the converter as it could be 30,40,45,55,60,80 amps). Once the batteries are charged, the converter will apply a trickle current to keep them there. (Learn something new every day). Now I can do my boondocking pre-testing ;-)
