Golf Cart battery sizes... Decisions, decisions

I used to have a pair of US145XC2 golf cart batteries on my Rockwood ROO until someone decided they wanted them more and stole them. So I know that a 250AH battery will be plenty. Since then I only put a single 12VDC battery on as we stopped boondocking for a while. Now we are planning on doing some more boondocking and now I need to figure out if a pair of 235AH golf cart batteries will be enough for my camper to go 3 days of dry camping or if I should go with the 255AH ones. $70 difference per battery is making me lean towards the smaller ones. Does anyone have any experience with Duracell golf cart batteries? I can get a corporate discount at Batteries Plus, and that's the brand they carry for this size.

    The 235s should be okay. Consider solar, even a small 100 watt system, and then you won't have any concern. What about a chain pulled tight around the battery boxes? Won't stop a committed thief but will a causal one.

    Summer camping only so furnace use should be minimal. I've replaced the overhead incandescent bulbs with LED boards too.

    Just depends on your usage. Furnace is the biggest load, but fridges are also in there. It's doable for sure.

    I use a voltmeter to measure the standing voltage in the batteries and you can chart the fall so you can really get an idea how much is there and how much is left before re-charging
