And that is just ME.. Oh and it is only a partial list of times I've been real happy I have like 500 amp hours of 12 volt.


How horrible for you, losing shore power like that. [emoticon] Funny, we lost power in Oct 2015 for 36 hrs when a freak snow storm blew in and took out power in the entire area. Funny, just one G27 battery to keep us going yet we're still here to talk about it. [emoticon]

I understand the OP does not boondock but if he has the room the bigger battery will simply give him more options. We are not talking a lot of money? What's the difference in cost $25.00 bucks. We are not talking going to an AGM or 2 Golf cart batteries.
Having the ability to run the furnace overnight with confidence, or connect a smaller inverter is a nice option to have. THe OP may find themselves stranded and need power? Never say never.
I use my RV in many ways and try to create as many options for myself as I can.

As always, you have heard lots of options. If you want to keep it simple, simply replace your 12v battery. Since you "never" dry camp you should be good to go.

If you want to improve things just a tad, replace your 12V with a true deep cycle battery, not a marine/deep cycle.

Of course you can continue up the ladder and get an AGM, a 31, two 12 volts, and don't forget solar power! Get a converter too while you are at it. How about a generator when the power goes out?

The answer to your original question is NO. Now go get something that works for you. Good luck in the hunt.

I appreciate the info. My local Sam’s had a sale on batteries so I bought a grp 27 AGM battery. I was going to opt for the 31, but my tongue is heavy enough as it is. The grp 31s are super heavy.

Maybe because it weighs 75-80 pounds. Can you lift it and place it where it needs to be? This is the reason many manufacturers provide dual Group 24 deep cycle batteries (about 45 pounds each) instead of one larger one, even though the pair is a slightly less reliable solution.

A G27 AGM (which the OP ended up buying) will typically average ~ 64 lbs, a G31 ~ 5 lbs more and nowhere near 75 - 80 lbs.
