Florida 6 Months winter.
Last night the lights would dim for a few minutes and then brightened up normal we had a few times she would not crank , no tick nada. I had already checked to convertor a few days ago and was good. I go do a look at the batts and one (that had went low on water) was gassing so bad i could see it. So turned my Aux. disconnect off. I know that Batt. is BAD. Question is should I switch from my Main and Aux or leave both on when on shore power? I have one Main #31 and two DC #24's I plan on replacing both Aux #24 now and the Main asap. 
 
I agree.. if the battery is gassing something fierce (sounds like a shorted cell to me) dump it (Disconnect) till you can replace.

NOTE: If it is one of a six volt pair REPLACE BOTH OF THEM the short could be in the other battery but in any case it is damaged.

  It was at night and dark so i used the disconnect switch I will replace both asap (same age) Can i wait a week Costco is 90 miles away. After i disconnected i had no more dimming of lights. I may go 6 volt? if cables will reach?
 
Up date checked Voltage 8.9(all three batt's) not good disconnected suspect/shorted batt and voltage took a few minutes to recover to 13.2 So converter seems ok. Can i wait till next week to replace both Aux. batts? Thinking i should be ok...
 
Well, you can't disconnect just one 6v battery - they have to be in pairs to produce 12v.

If you have 3 batteries, I'm guessing that one is 12v (engine starting) and the two for the house are a pair of 6v in series. So which did you disconnect?
