I don't really know anyone but maybe if you explain what you are trying to do we could walk you through it . Costco has deep cycles RV batteries which aren't hard to replace . I do know there is mobile RV guys but getting them there right away might be difficult.

The only true deep cycle batteries that Costco has, are 6v and 8v golf cart batteries.
Their Intetstate 12v RV batteries are dual-purpose marine batteries, which are not true deep cycle batteries. They have a CCA rating for starting motors.
Never seen AGM batteries at any of my Costcos. If they have them, then that would be a true 12v deep cycle battery.

The VAST majority of AGM's sold are also dual purpose models. Only Golf Cart AGM's...are virtually guaranteed to be true deep cycles regardless of brand unless you are going to premium AGM's like Trojan and Lifeline.

I'm afraid you won't find anything like those at any of the big box stores. You have 4D size batteries which generally weigh over 130lbs each and provide roughly 200 amp hours at 12Volts EACH...so you have about a 400 amp hour bank of batteries. And about a $1000 price tag to buy again. Marine Stores and Truck Stops would be the most common places to fine this size battery.
But the first thing to do is to make sure they are toast. To do this you need to either take them to an automotive store (like trac auto, autozone) for load testing... or get someone handy with a multimeter to come to your coach and inspect the battery condition AND the charging system/converter system operation. If you have your own multimeter and can use it we can give you some things to check.
Good luck.
