I may have misinformed the group by talking about amp hours. I will be using the batteries with less draw as my new trailer will have led lighting. Just trying to figure out if the benefit of one battery will do the job if draw will be reduced. I was able to go through the links that were sent, thank-you, and I believe my usage is probably about 75 amp hours in typical day, then with generator running etc. I may be ok with one battery. This taken into consideration that the AGM may drain power at the same rate as typical wet cell, but will charge faster???? Things that make you go HMMMMMMMMMMMMMMM.I have talked to a few "Sales People" Interstate, Napa, Batteries Plus and even Sam's Club, AGM charging and draw seem to be better by their opinion due to the manufacture education they received. Again, things that make you go HMMMMMMMMMMM..... Thanks all, I will keep reading and if you have more info, I will take it!!!!
