Battery question

Checking voltage requires a voltmeter. I picked up a nice little one that plugs into a 12 volt cigarette lighter outlet, which my TT has next to the TV connections. It cost about $10 at an RV dealer. For about the same cost, you can get a fairly low-end VOM (aka volt-ohm meter) from Radio Shack which will also read voltage (among other things), although it's not as simple and convenient as the one that plugs into the cig lighter.

I'm sure that the plug-in meter works well for you but a hand-held meter has it's place in the tool box. It has more functionality and measures at the location, not through any switches, relays, or lengths of wire which can effect the accuracy of what's being measured. I think some folks shy away from buying a hand-held because they've never used one and are afraid of a steep learning curve or inability to using one. If you can't use a meter, you probably shouldn't be mucking around with electrical systems anyway. They are not that difficult to use.

Charger settings: 2 amp for maintenance use. You may want to disconnect the TT's 12v system from the batteries so that you're not powering up circuit boards and alarms.
