If bad replace with 2 6 volt Golf Cart batteries (wired in series to make 12 volts) from Costco or Sam's Club as enblethen suggested.
Why would he do that? :h The OP said in his original post -
"We do NOT dry camp but we do overnight sometimes in a rest area to get some sleep. We use the lights to get ready for bed. Once in bed no lights are on. The refrigerator is on propane. Once in awhile, we will take quick showers to freshen up. Water heater on propane." That being the case he has absolutely no need for dual 6 volt GC-2 batteries when his single 12 volt will serve his purposes just fine, particularly if his rig is equipped with LED interior lighting which draws very little. It would also help enormously to turn off the fridge climate control heating element which is an unnecessary load on his battery. Rather than wasting $$$ upgrading his battery what he
should be doing is find the source of this draw down on his battery
even when his battery disconnect switch is off. Somethin' ain't right and upgrading his battery isn't going to solve it, fixing the problem will. ;)
