I keep my rig at a storage area under roof between frequent trips. In effect, it is on it's own for power as there are no available 120v power sources at the storage facility. Because of that, I keep the rig powered down and the 12v disconnect switch off. I visit it quite often and when doing so, bring my Honda 2000i generator along, hook up with the 50 - 30 adapter, turn on the 12v disconnect for the few hours I am there.

Just recently, I arrived a day before a four day trip to turn on the 12v and propane to cool the refrigerator down by the next day. When I returned next day, refer was only a little cool, and the 12v battery so dead that I could only get a light to glow. My meter was in a drawer covered by a slide so I couldn't tell how badly discharged it was. Given the phantom 12v pull down and the refer needing 12v, a single 12v battery is not enough in this situation.

I am currently converting to 2 T-105 golf cart batteries and building an enclosure to contain the batteries. This I have always done on my Cruising Boats. If the factory supplied converter can take a plug in intelligent 3 stage charge module, I'll add that. If not, then add a Xantrex True Charger. Will let you know how this works out.

My Monty is not under roof, and I have Solar panels, which keep the batteries at 100%. My Solar Controller has voltage and temperature sensor, so I don't have to worry about over charging. I have Six T-105 and love them. Maintenance has been easy, and haven't use much water in six months.

You might check your converter model specs as the converter on my 2011 already has the variable charge capability as purchased. The IOTA converter on my 2005 didn't so I added the plug in 3 stage charger control.
