Disagreements are inevitable, but we can all share our knowledge, experience and results of research. And I respectfully disagree if you are suggesting that the average RV user can expect eleven years from the house battery. Sure - you might get there with great care and little use, but it will be an outlying case, or it will be so weak by then that most anyone would be replacing it. That is not just my opinion either, its the information I have gleamed from experts in the field.

While I do not have the long term camping experience with batteries many here have, I have been messing around with batteries in vehicles for several decades and have formed some opinions on them (sorry for the run-on sentence).

Generally, I feel bigger is better. The 27 is not that much bigger or heavier and might just give a little more cushion in electrical capacity so why not? That said, I think the component missing from the discussion so far is what KIND of battery is it? All batteries are not created equal to all tasks. You want a true deep cycle battery. I don't know what Scamp is providing, but they probably have it figured out.

OK, wait till spring when the stores and sporting goods stores put them on sale for fishermen. We got a group 27 battery for $84.95!

Diane is talking about an AGM battery. My first one lasted 8 years until someone left the fridge on 12 volts over night ( I blame the dog ). They are rated for up to 1000 charge/discharge cycles (which is about twice the standard wet cell) and have an extremely low self discharge rate. I recharge mine once in the off season. I have one because they are very safe, which makes the very high cost worth it to me. I'm hoping for 10 years. I'll let you know. Raz

So do two GC2 (golf cart) batteries which are more capacity, but also more tongue weight.

76 AH vs 89 AH so the Group 27 has 13 more AH than 24 or about 20%. Weight difference is about the same %. About 1/3 to 1/2 of these AH are useable, depending on how you charge them.

Plugged in it don't matter, but for dry camping you must figure YOUR usage of power and how you are going to charge.. To many variables here to make recommendations.

I have two trojan group 24 in my Bigfoot TC with 140 watts of solar and it is just fine, but I am careful. I do some off season (eg need furnace) dry camping and watch DVD's n the evening, so do use a bit of power.

Remember one thing. If you go to small and run the battery down, then you will be replacing it much sooner.. And if you really want to manage things you need a good monitor or volt meter to keep tabs on things.

AND I have never ever seen a battery in an RV go 11 years for nobody nohow. The environment is to unpredictable with humidity, temperature swings, uneven discharge and charge rates etc. it just don't happen. Just saying. ESPECIALLY with solar panels which do a charge/discharge cycle every day they are hooked up.

IMHO, of course.

Not an RV battery but when the battery in my Ranger, that I bought new in '02, started getting weak I was really surprised to find it was still original and 11 years old. Guess I got a lemon as it lasted so long . That was a first.

24 weighs about 50 lbs and a 27 weighs about 60.
