I checked on the price of a 270 amp-hour jar. $1,419.92 Cdn. Weight 154.3 lbs. Too rich for my blood.
Don,
That's why I gave the link in my post above to the 76 lb. Soneil Group 31 battery model ... as it's easier to lift 76 lbs. twice instead of 154.3 lbs. once. Of course the price for that heavy Soneil battery is absurd, too.
As far as AGM performance is concerned versus what they cost for RV use, I got around 8 years of service out of a couple of Group 29 12V Interstate AGM wheel chair batteries before I replaced them with my two Fullrivers. The Interstates were still performing pretty good, but I replaced them at the 8 year point "just in case".
The price you show for the heavy Soneil is getting into lithium range, but of course lithium batteries still have a problem that I can't accept even if I could accept their pricing ... as I understand it lithiums can't, or shouldn't, be recharged in low ambient temperatures. :h
P.S. I'm still getting by 24/7/365 with mostly the stock 13.8 volt converter and Ford engine alternator for taking care of our RV's AGM batteries. I guess I must be lucky. ;)
