My new Rockwood came with two Exide batteries, 12v wired in parallel. I've thought about going to 6 volt batteries in series but they are too heavy for me to lift in and out of my 5th wheel...not to mention the cost. I'm interested in everyone's opinion on the best brand and configuration. I've looked at Trojan 27TMX and SCS225 and other brands like Interstate and Exide. Haven't been too impressed with my current Exides. Someone also told me about "Deka Marine/RV" but haven't ever heard of it. Any thoughts and opinions would be greatly appreciated.

The Trojan SCS225 weighs 66 pounds while T105 comes in 62 so why are you considering the SCS225? The Trojan 27TMX Is 55 however.

I prefer interstates. I have used them for years in my boats now campers. IMO they are the best bang for your buck. When I went up to a group 29 on my pop up, I went with exide. After a year, it would not raise the roof - switched back to interstate and never had that problem again.

I think many GC2 are 62-65 pounds and 12 volts are probably about the same. Biggest issue with gc2 is head room. How are you using you RV? In campgrounds a lot? How much dry camping? How much inverting?

I have been using Trojan SCS series batteries since 2005. They are higher quality, weight and AH capacity compared to generic 12V deep cycle batteries. They do of course cost more. We do fine with a single SCS 200 when we dry camp for 2 weeks. We need 12V power for fans, water pump, fridge etc. No inverter use and we charge daily.

If you always camp with hookups then just get 1 cheap 12v battery. If you camp a lot with no place to plug in then 6v would be the way to go.I really like Deka batteries we use them a lot in the solar systems we build. I've installed literally hundreds of them with good results.
