I call $180 a fantastic deal for that capacity. If I had room, I'd double up to 4 batteries for 214 AH. I don't think there's a better deal anywhere than $360 for 200+ AH... Lead-acid is 100 year old technology, but still hangs around like utility poles. They're still the overwhelming choice in power backup systems because of its time tested reliability.

It is a good deal but there is now a better one: Interstate GC 12. 150 ahr each at 12 v so 300 ahr total. About same size as GC2s…but heavier.
I plan to get a couple by next winter. Costco lists them for $249 each, but never has them. Local Interstate has them but wants $299 each. I’ll pay that if Costco still out in the fall.
My crappy new 12 v “deep cycle” batteries OK in summer when solar can recharge them during day. And running generator for AC recharges them.
I need the extra power to run the heater in the winter. Solar useless here in winter when daylight is short and sun angle low.
I rarely camp with shore power: like one day per year. And I use the RV about 100 days per year.
