I had 2 X group 24 interstate deep cycle batteries and they were rated at 75AH each, the Duracell GC2 I replaced them with are rated at 230AH, so I went from 150AH to 230, much happier, I could not run the furnace through the night with the G24s, unless I set the thermostat to 40 or 50.

This season I have a 100 watt solar panel to add to the mix.

The bigger size would give me more reserve amps without going to 6v batteries which would cost more. Looking at Interstate deep cycle batteries. Also would the maintenance free be better than the regular?
I would suggest measuring the space for the batteries available on your Passport. Even if you have to buy new boxes you will be better off with 2 batteries if they will fit. A 6v system requires two batteries to get to 12v. Either way you are now able to expand your RV experience to include those places (like Forest Service and National Park campgrounds) that don't offer full hook-ups. We find ourselves dry camping and boondocking a lot. I think it puts us closer to the action. Once you're ready give it a try

Just got on the forum to look into battery options. Not trying to hijack the thread, but I was about to buy a second group 24 battery to add to my Cougar because we dry camp often and my single battery doesnt last very long. Is the popular option to get two 6v golf batteries instead of two 12v deep cycle batteries? If so, why?

Yes, it was mentioned earlier. The total capacity of 2 - 6v batteries is better than 2 - 12v. In addition, they are true deep cycle.

In your case, you would want to buy 2 new batteries. If you have a Costco, you can get 6v GC2 batteries for around $80 a piece.
