So trying to find the sweet spot with some sense of knowledge...LOL.
If I am correct I may be able to put up to 3 of the AGM in the same space as the wet cells.
I've been looking at CHIN and Duracell ultra premium 100 to 105AH... See this I am already getting better.... Hahaa the average price I see is around $240 per battery. If I am correct the safe feeling is well worth the money.
If you want to feel free to pass onto those you trust as it can only help me in my decision.

AGM and flooded batteries use the same chemistry, so the number of cycles and depth of discharge are the same. Since AGM batteries have absorptive glass mats between the plates there is less room for lead in the battery case, resulting in a slightly lower amp-h capacity for a given battery case size. The major advantages of AGMs over flooded are any position mounting, no watering and low self-discharge. You may read many other claimed advantages of AGMs but careful reading of the Trojan and Lifeline specifications show little differences in the capabilities of AGM and flooded batteries.
Lithium-iron-phosphate batteries (LFP) are in every way superior to all other batteries for RV use remembering they should not be charged when they are below freezing. This should not be a problem for most. LFP batteries do require a different charging profile (usually a new charger and BIM).
