Requesting solution from knowledgeable RV.NET collective

Need to replace 2yo T-105s due to my neglect and wondering if 2-12V 24DC in parallel are a wiser less expensive choice since not using MH dry- camping? https://www.walmart.com/ip/EverStart-Lead-Ac...

If you hook up 2 12V to create a 24V circuit you will blow up everything 12V in your coach. Please DO NOT DO THIS!
You certainly could do 2 12V batteries wired in parallel to maintain a 12V output and increase the amp hours. Compare the amp hours of the 2 6V wired in series to the amp hours of your 2 batteries wired in parallel to compare the 2 options.
2 6V of 100 amp hours = 100 amp hours at 12V
2 12V of 100 amp hours = 200 amp hours at 12V
