I have been struggling with this and have not even bought the RV yet

If I follow the new batteries you just bought have 105 AH reserved so I assume you now have 105AH/20H = 5.25 A you can pull from battery over 20 hours?
Did the battery actually list total reserve capacity?

Do you know what your original batteries were as for as reserve capacity goes?

If it makes you feel better, I spoke with Worldwide Battery a few weeks ago who advised me to go with two 12 volt AGM Group 31 versus the 6volt batteries in series. I am sure you have done the right thing. Worldwide's factory battery for Thor ACE is 90 AM & 180 Reserve Capacity. They have a 12v battery with more reserve capacity at 225? To compare like for like, I would need to know Reserve Capacity for Duracell. As long as cost is in $250 range, I would try to get the one with the most reserve capacity which is my primary concern.
