2018 Thor Chateau 31W Class-C. During the first year, it was in and out of the dealer repeatedly, and each time they left the house battery switch on, so invariably, they'd be dead as a door nail when I picked it up.
The two house batteries will only keep the residential fridge going for 10-hours before kicking the inverter offline. Other owners tell me it should be a lot more, even without solar.
I'm thinking of replacing the two 12v batteries with FOUR new ones (since the rack holds four). My question is: Does the charging system have any switches or adjustments that need to be made when going from two to four batteries, or does it just feed power to them until they're happy?
Eventually, I'd like to add solar and lithiums, but that's a whole other kettle of fish that I'll deal with when I can afford it. For now, I just need to know if there's anything I need to do aside from letting the system do its thing. Many thanks!! You guys rock!

I replaced the 2 batteries in my 2018 Thor Windsport 29m after almost 3 years. I upgraded our Norcold fridge to a 12v system from JC Refrigeration in Indiana and love it. Problem was the batteries wouldn't stay above 12v over night when boondocking because the fridge gets power from the batteries only. I got AGM's at first and did not see ANY improvement. Napa refunded me the difference on there flooded RV/Marine batteries and they worked OK but still needed more amps. I removed the metal plate in front of the battery and the hold down and access hole piece so the tray was flat and easily installed a 3rd battery. WORKS GREAT!!!!!!!!!!!!!!!! Also I'd highly recommend the Quick-Fill system. Low water in batteries is a death sentence and it is sooooo much easier than trying to fill them with a battery fill bottle. Just attach the hose, put the end in a gallon of distilled water and pump til it's full. You can replace flooded batteries twice for the cost of AGM's and I swear I didn't see any diff!!!! Bob Trice
