Wade,
I once knew the ah ratings of my batteries but I have forgotten what it is now. I have 2 Interstate 27 series deep cycle batteries on the hitch and a cheaper sealed deep cycle unit inside. I serviced the hitch batteries yesterday and on the top it had a sticker with 750 on it so I assume they are 750 amp hours. Does that sound right? I think I wrote the info down in my "Solar Power Your RV" book by Noel Kirkby but I lent it to a friend.
Having the sealed unit inside works out well as that battery is so difficult to get to.
